Can 100% renewable energy power the world? - Federico Rosei and Renzo Rosei
Check out our Patreon page: https://www.patreon.com/teded View full lesson: https://ed.ted.com/lessons/can-100-renewable-energy-power-the-world-federico-rosei-and-renzo-rosei Every year, the world uses 35 billion barrels of oil. This massive scale of fossil fuel dependence pollutes the earth, and it won’t last forever. On the other hand, we have abundant sun, water and wind, which are all renewable energy sources. So why don’t we exchange our fossil fuel dependence for an existence based only on renewables? Federico Rosei and Renzo Rosei describe the challenges.

What is energy for kids | Learn about Energy Sources | Renewable Energy |  الطاقة | エネルギー | zaffron
This video represents a good explanation of What is energy for kids. You will gonna learn about Energy Sources for kids, How we use Energy ( how to save energy ) and a brief understanding about different types of Renewable Energy resources as well as the nonrenewable ones. ► What is energy ? The best definition of energy, that every children should know, is that the Scientists define energy as the ability to do work. Modern civilization is possible because people have learned how to change energy from one form to another and then use it to do work. We use energy to move cars along roads and boats through water, to cook food on stoves, to make ice in freezers, and to light our homes. Energy comes in different forms: Heat (thermal), Light (radiant), Motion (kinetic), Electrical, Chemical, Nuclear energy and Gravitational Energy. People use energy for everything from making a jump shot to sending astronauts into space. There are two types of energy: ( Stored (potential) energy + Working (kinetic) energy ). For example, the food a person eats contains chemical energy, and a person's body stores this energy until he or she uses it as kinetic energy during work or play. Energy sources can be categorized as renewable or nonrenewable When people use electricity in their homes, the electrical power was probably generated by burning coal, by a nuclear reaction, or by a hydroelectric plant on a river, to name just a few sources. Therefore, coal, nuclear, and hydro are called energy sources. When people fill up a gas tank, the source might be petroleum refined from crude oil or ethanol made by growing and processing corn. Energy sources are divided into two groups: 1- Renewable (an energy source that can be easily replenished) 2- Nonrenewable (an energy source that cannot be easily replenished). ► Renewable energy and nonrenewable energy for kids : Renewable and nonrenewable energy sources can be used as primary energy sources to produce useful energy such as heat or used to produce secondary energy sources such as electricity. When people use electricity in their homes, the electrical power was probably generated from burning coal or natural gas, a nuclear reaction, or a hydroelectric plant on a river, to name a few possible energy sources. The gasoline people use to fuel their cars is made from crude oil (nonrenewable energy) and may contain a bio-fuel (renewable energy) like ethanol, which is made from processed corn. ► Moreover, you will gonna learn What is renewable energy for kids ? There are five main renewable energy sources: 1- Solar energy from the sun 2- Geothermal energy from heat inside the earth 3- Wind energy 4- Biomass from plants 5- Hydro power from flowing water ► What is Nonrenewable energy ? Most of the energy consumed in the United States is from nonrenewable energy sources: ( Petroleum products - Hydrocarbon gas liquids - Natural gas - Coal - Nuclear energy ). Crude oil, natural gas, and coal are called fossil fuels because they were formed over millions of years by the action of heat from the earth's core and pressure from rock and soil on the remains (or fossils) of dead plants and creatures like microscopic diatoms. Most of the petroleum products consumed in the United States are made from crude oil, but petroleum liquids can also be made from natural gas and coal. Nuclear energy is produced from uranium, a nonrenewable energy source whose atoms are split (through a process called nuclear fission) to create heat and, eventually, electricity. By watching this video, you will gonna learn how to conserve energy resources ( energy saving ) by understanding how energy conservation mechanism work as well as much knowledge about alternative energy resources. Enjoy watching and have a great time learning about energy sources for children.

How are fossil fuels formed?
CBSE class 10 Science - Sources of energy - Petroleum, Coal, Natural Gas are all known as the fossil fuels. Formation of fossil fuels happened millions of years ago. The dead plants and animals got buried into the oceans and rivers, and with the effect of Pressure and Temperature broke down into simpler products and the final product was the fossil fuels. Coal was formed by the remains of the plants whereas the Petroleum was formed by aquatic marine life. Since it takes millions of years in the formation of the fossil fuels hence these are non-renewable sources of energy. Petroleum products are generally used for running the vehicles and the coal is majorly used in the thermal plants to generate electricity.

Non-Renewable Energy Resources | GCSE Physics | Doodle Science
Follow me!: https://twitter.com/DoodleSci Doodle Science teaches you high school physics in a less boring way in almost no time! Script: Fossil fuels are non-renewable energy resources; these are coal, oil and natural gas. They were formed from the remains of living organisms millions of years ago and they release heat energy when they are burned. This heat is used to turn water into steam, which is used to turn a turbine, which then drives a generator to generate electricity. There are downsides however, fossil fuels release sulphur dioxide and carbon dioxide which lead to acid rain and an increase in global warming. Another form of non-renewable energy is Nuclear. The main nuclear fuels are uranium and plutonium. The nuclei of these large atoms are split in a process called nuclear fission to release a great deal of heat. The heat energy is again used to boil water. The kinetic energy in the expanding steam spins turbines, which then drive generators to produce electricity. Unlike fossil fuels, nuclear fuels do not produce carbon or sulphur dioxide. However, they do have the risk of a fault where large amounts of radioactive material could be released into the environment such as the disaster of Chernobyl in 1986.

To answer these questions, we need to understand what makes energy, or anything else for that matter, cheap and plentiful. For something to be cheap and plentiful, every part of the process to produce it, including every input that goes into it, must be cheap and plentiful. Yes, the sun is free. Yes, wind is free. But the process of turning sunlight and wind into useable energy on a mass scale is far from free. In fact, compared to the other sources of energy -- fossil fuels, nuclear power, and hydroelectric power, solar and wind power are very expensive. The basic problem is that sunlight and wind as energy sources are both weak (the more technical term is dilute) and unreliable (the more technical term is intermittent). It takes a lot of resources to collect and concentrate them, and even more resources to make them available on-demand. These are called the diluteness problem and the intermittency problem. The diluteness problem is that, unlike coal or oil, the sun and the wind don’t deliver concentrated energy -- which means you need a lot of additional materials to produce a unit of energy. For solar power, such materials can include highly purified silicon, phosphorus, boron, and a dozen other complex compounds like titanium dioxide. All these materials have to be mined, refined and/or manufactured in order to make solar panels. Those industrial processes take a lot of energy. For wind, needed materials include high-performance compounds for turbine blades and the rare-earth metal neodymium for lightweight, specialty magnets, as well as the steel and concrete necessary to build structures -- thousands of them -- as tall as skyscrapers. And as big a problem as diluteness is, it’s nothing compared to the intermittency problem. This isn’t exactly a news flash, but the sun doesn’t shine all the time. And the wind doesn’t blow all the time. The only way for solar and wind to be truly useful would be if we could store them so that they would be available when we needed them. You can store oil in a tank. Where do you store solar or wind energy? No such mass-storage system exists. Which is why, in the entire world, there is not one real or proposed independent, freestanding solar or wind power plant. All of them require backup. And guess what the go-to back-up is: fossil fuel. Here’s what solar and wind electricity look like in Germany, which is the world’s leader in “renewables”. The word erratic leaps to mind. Wind is constantly varying, sometimes disappearing completely. And solar produces little in the winter months when Germany most needs energy.

You Are Watching: TOP 10 ALTERNATIVE SOURCES OF RENEWABLE ENERGY OF THE FUTURE 🔥🔥🔥 in 2018-2019 he potential issues surrounding the use of fossil fuels, particularly in terms of climate change, were considered earlier than you may think. It was a Swedish scientist named Svante Arrhenius who was the first to state that the use of fossil fuel could contribute to global warming, way back in 1896. The issue has become a hot-button topic over the course of the last few decades. Today, there is a general shift towards environmental awareness and the sources of our energy are coming under closer scrutiny. This has led to the rise of a number of alternative energy sources. While the viability of each can be argued, they all contribute something positive when compared to fossil fuels. Lower emissions, lower fuel prices and the reduction of pollution are all advantages that the use of alternative fuels can often provide. Here we examine eleven of the most prominent alternative fuel sources and look at the benefits they offer and potential for increased uptake in the coming years.

Renewable Energy Resources: Part 1 | GCSE Physics | Doodle Science
Follow me!: https://twitter.com/DoodleSci Doodle Science teaches you high school physics in a less boring way in almost no time! Script: Renewable energy resources are being developed because we are running out of fossil fuels at an exponential rate. The wind is produced as a result of giant convection currents in the Earth's atmosphere, which are driven by heat energy from the sun. Wind turbines use the wind to drive turbines directly. The blades are connected to a housing, which contains gears linked to a generator. As the wind blows, it transfers some of its kinetic energy to the blades, which turn and drive the generator. The advantages are that there are no fuel costs and no harmful pollutant gases are produced. However, they depend on wind, if there is no wind, there's no electricity. Like the wind, water can be used to drive turbines directly. Wave machines use the kinetic energy in this movement to drive electricity generators. Another way of using the water is to build a tidal barrage over a river estuary to make use of the kinetic energy in the moving water. The barrage contains electricity generators, which are driven by the water rushing through tubes in the barrage. Hydroelectric power stations are dams built across a river valley. The water high up behind the dam contains gravitational potential energy. This is transferred to kinetic energy as the water rushes down through tubes inside the dam. The moving water drives electrical generators, which may be built inside the dam. Water produced energy is good because no harmful polluting gases are produced and tidal barrages and hydroelectric power stations are very reliable and can be easily switched on. However, tidal barrages destroy the habitat of estuary species and hydroelectricity dams flood farmland and push people from their homes.

Freedom from fossil fuels is closer than you think  | Dhruvik Parikh | TEDxSnoIsleLibraries
You might be wondering what a high school student can do to help address climate change. In his fascinating talk on his experimental research into energy independence, Dhruvik Parikh offers unique theories in the form of agricultural waste and “close-looped” systems where the waste of production can be used to fuel the next round of production creating local systems that are self-sustaining. Dhruvik also addresses concepts for community access to clean water and energy storage where whole communities work to develop their own collective renewable energy system. By examining the environmental and economic considerations of harnessing energies already available, Dhruhvik sees a future where cities can be self-sustaining and communities can thrive. Student at Henry M. Jackson High School, Mill Creek, Washington. Participant in a variety of clubs including the Technology Student Association and MIT Launch Club. Co-founded startup, Travalot, at the prestigious MIT Launch startup incubator. Managed strategy and operations for the company. Interested in finding solutions to the energy storage conundrum.

Renewable Energy: It Uses Practically No Water Compared to Fossil Fuels
The Energy Information Administration (EIA) recently highlighted a little-discussed benefit of using renewables like wind and solar to produce electricity: Unlike most power sources, they require “almost no water.” This is remarkable because thermoelectric power generation is the leading use of water in America. (That said, only three percent of power generation's 133 billion gallons a day of water is considered “consumptive use,” as the U.S. Geological Survey says, “meaning it is lost to evaporation or blowdown during generation.”) According to the latest U.S. Geological Survey (USGS) data from 2015, 41 percent of the water used in America is for power generation. The next highest use is irrigation for agriculture, accounting for 37 percent of U.S. water use (and close to two-thirds of that is consumptive). The Union of Concerned Scientists was raising this alarm in 2012 when the nonprofit created an infographic focused on the “energy-water collision,” which “refers to the range of issues that can crop up where our water resources and our power sector interact.” That can include increased competition for dwindling water sources and problems when the water going into or out of power plants is too warm. Why does producing electricity require so much water? As the Department of Energy (DOE) notes: “The main demand for water within a thermoelectric power plant is for condensing steam. Thermoelectric power generation typically converts the energy in a fuel source (fossil, nuclear, or biomass) to steam and then uses the steam to drive a turbine-generator.” This varies somewhat for natural gas, depending on the type of turbine. With many areas of the world, including large parts of America, already dealing with droughts and water shortages — problems expected to be exacerbated by climate change — the water intensity of power sources becomes another factor for local, state, and regional planners to consider. Coal’s Decline Brings Slight Progress The recent topline analysis from the EIA about water use for all energy sources in America is encouraging. Since 2014 the amount of water used to produce energy has been steadily declining. USGS data show this has been the trend since 2005: “The 2015 estimates put total withdrawals at the lowest level since before 1970, following the same overall trend of decreasing total withdrawals observed from 2005 to 2010.” Over a five year period from 2010 to 2015, water use for power generation dropped 18 percent. Much of this drop can be attributed to the decline in coal as a fuel source for electricity generation, as well as power plant closures and new plants implementing more water-efficient technologies. However, while the decline of the coal industry has meant power plants overall are using less water in the U.S., some of the power sources that are replacing coal, namely natural gas, are still highly dependent on water. While the natural gas industry’s claim that methane-rich gas is a cleaner “bridge fuel” to the future — an argument thoroughly debunked when accounting for globe-warming methane leaks in the supply chain — water use is another reason to consider wind and solar power over natural gas. Due to the various technologies used in natural gas power plants, some are more highly dependent on water than others. This variation makes it difficult to quantify just how much water natural gas power generation uses as a sector compared to coal. However, it is safe to say that natural gas power production uses less water than coal in general. Thus, the switch from coal to gas is contributing to the overal decline in water use for power generation, as the USGS and DOE say. As solar and wind become increasingly cost competitive with natural gas for electric power generation — especially in water-constrained areas of the country — they have the added advantage of being a water smart choice.

What if I also told you that this energy source was cheap, plentiful, and reliable? Well, there is such a source. You probably know it as fossil fuel. Oil. Natural gas. Coal. But wait? Don’t fossil fuels pollute our environment and make our climate unlivable? That, of course, is what we’re told…and what our children are taught. But let’s look at the data. Here’s a graph you’ve probably never seen: the correlation between use of fossil fuels and access to clean water. More fossil fuel. More clean water. Am I saying the more we that we have used fossil fuel, the cleaner our water has become? Yes, that’s exactly what I’m saying. In the developed world, we take clean water for granted. We turn on a tap and it’s there. But getting it there takes a massive amount of energy. Think of the man-made reservoirs, the purification plants, the network of pipes. In the undeveloped world, it’s a much different story. They lack the energy, so they lack clean water. More fossil fuel. More clean water. The same is true of sanitation. By the use of cheap, plentiful, and reliable energy from fossil fuels, we have made our environment cleaner. Take a look at this graph. More fossil fuel. Better sanitation. Okay, what about air quality? Here’s a graph of the air pollution trends in the United States over the last half century based on data from the Environmental Protection Agency. Note the dramatic downward trend in emissions, even though we use more fossil fuel than ever. How was this achieved? Above all, by using anti-pollution technology powered by…fossil fuel: oil, natural gas and coal. But even without modern pollution control technology, fossil fuel makes our air cleaner. Indoor pollution—caused by burning a fire inside your house, cabin, hut or tent to cook and keep warm—was a deadly global problem until the late 19th century when cheap kerosene, a fossil fuel byproduct, became available in America and Europe. Indoor pollution is still a major issue in the developing world today. The best solution? Fossil fuel. And now we come to the biggest fossil fuel concern of all—global warming. On this very sensitive topic we need to get our terms straight: There is a big difference between mild global warming and catastrophic global warming. We can all agree on that, right? The issue isn’t: does burning fossil fuel have some warming impact? It does. The issue is: is the climate warming dangerously fast? In 1986 NASA climate scientist James Hansen—one of the world’s most prominent critics of the use of fossil fuels—predicted that “if current trends are unchanged,” temperatures would rise 2 to 4 degrees in the first decade of the 2000s. But as you can see from this graph, since 2000 the trend line is essentially flat—little or no warming in the last 15 years. That’s probably why we hear much less talk about “global warming” and much more talk about “climate change.” For the complete script, visit https://www.prageru.com/videos/fossil-fuels-greenest-energy

Since the industrial revolution, the combustion of fossil fuels, accounting for 87% of today’s global energy package, has replaced biomass as the primary source. Yet issues surrounding energy and food production and sustainable development engender new perspectives on the production of bio-fuels, especially from by-products of agro-industry and forestry. Biomass, now supporting 10% of world energy consumption, could increase to provide 25% of global energy needs. This film combines figures, schematics, and interviews with professionals in the field (e.g. economist, farmer, mechanic, researcher, aircraft manufacturer...). The potential for biomass is evident, but its usage must be rational, optimized and adapted to local environments. A film by Gérard Goma (scientific advisor) and Mathias Fyferling

alternative source of energy
Image result for alternative source of energy Commonly known alternative energy sources Hydroelectric Energy. Solar Energy. Wind Energy. Biomass Energy. Geothermal Energy. Tidal Power.Alternative energy is any energy source that is an alternative to fossil fuel. These alternatives are intended to address concerns about such fossil fuels, such as its high carbon dioxide emissions, an important factor in global warming. Marine energy, hydroelectric, wind, geothermal and solar power are all alternative sources of energy. The nature of what constitutes an alternative energy source has changed considerably over time, as have controversies regarding energy use. Because of the variety of energy choices and differing goals of their advocates, defining some energy types as "alternative" is considered very controversial

Power stations and the national grid | Electricity | Physics | FuseSchool
The flick of a switch, that’s how easy it is to get electricity, right? If you’re one of the lucky ones, then yes. But in 2017 there are still over 1 billion people who do not have access to electricity. In this video we will discuss how electricity is generated and transferred to our homes, for those of us fortunate enough to have it. There are a variety of ways in which electricity is generated or made. How many can you think of? Solar panels, Wind turbines, Biomass, hydroelectric, nuclear and fossil fuels And then there is also geothermal energy, tidal power and wave power as well. Except for burning fossil fuels and nuclear, the rest are renewable sources of energy. Currently about 80% of the world’s energy comes from fossil fuels. First, we’re going to have a look at burning fossil fuels in power stations, to generate energy. And then we’ll look at the national grid - which is relevant for both non-renewable and renewable energies. Fossil fuels in power stations. Most power stations use coal as an energy source, and they work in the following way. Coal is burned in a power station. The heat produced as the coal burns is used to heat water. The water boils and turns into steam. This steam is used to turn the blades of a turbine. A turbine looks like a fan or a wind turbine. The turbine turns a generator. Inside, wires turn within magnets to generate electricity. So that was a fossil fuel power station. These next steps are for energy generated from any source - whether it’s fossil fuels or renewable like wind-powered substations or biomass fuelled. The electricity, whether renewable or not, is passed through transformers and wires, within the national grid, that carries it to our homes. So, what exactly is the National Grid? The National Grid is a system of cables and transformers linking power stations to consumers. Have you ever felt an electrical wire and noticed it gets hot? This is because some energy travelling through the wire is lost as heat. In order to lose as little energy as possible, transformers are used. When the electricity leaves the power station it passes through a step-up transformer. Power station @ 25,000 V A step-up transformer increases the voltage and reduces the current. National grid cables @ 275,000 V Reducing the current makes the transfer of electricity more efficient, as less energy is lost as heat. Before the electricity gets to our homes, the voltage needs to be reduced back down to a safe level. The electricity therefore passes through a step down transformer. Household @ 230 V So, now you know how electricity is generated and sent to our homes, it’s not quite as simple as flicking a switch. Quite a lot of infrastructure is needed.

Renewable Energy in Cyprus
What is energy? -The ability to do work, a physicist would say. The ability to move, walk, cook, drive a car, use a computer, turn on the lights. All these actions require energy. -Most of the energy we exercise comes from fossil fuels. Petrol, kerosine,natural gas etc. provide us with energy. Usually we convert the chemical energy of the fuels to electricity by burning them. This however produces large amounts of Carbon Dioxide which are released in the atmosphere, enhancing the greenhouse effect. -In order to decrease the emissions of carbon dioxide, other alternative, renewable and green sources of energy must be used. Such energy sources include: Hydroelectricity Solar energy Wind energy -Here in Cyprus though we cannot effectively use Hydroelectricity since there are no medium to large rivers to harvest their potential energy. -Although wind energy has started to be used in Cyprus, it accounts for a small percentage of electricity produced, and large scale electricity production wind energy is improbable. -Solar energy is used to heat water (for house utilities) virtually in every house. However solar energy in Cyprus can be used much more extensively. -So, since Cyprus has sunshine during most of the year (at least 300 days a year and 3300 - 3500 sunshine hours a year), solar energy has the potential to power the entire island. -Even though the efficiency of solar cells is fairly low (up to 14%) it can be effectively used in Cyprus, either in large scales or for individual households. Even though solar cells are expensive, in the long run they can cover their own costs and even provide profit, since the electricity costs of the house can fall to zero To conclude solar energy has the potential to achieve the desirable amount of energy required to power the whole island and to meet the expectations of the European union.

Examples of Renewable Resources
Visit us/get in touch at: http://wastersblog.com/1653/examples-of-renewable-resources/ We provide Examples of Renewable Resources: A renewable resource is one that replaces itself normally at a rate equal to or higher than human usage. The term normally refers to renewable energies, which are self-sustaining in time. There are 5 primary kinds of renewable resources, solar, wind, hydropower, geothermal and biomass. Many countries today are increasing their use of renewable energies to change fossil fuels, such as coal and petroleum, which take thousands and occasionally millions of years to change themselves, making them non-renewable resources. Examples of non-renewable resources are fossil fuels, like coal, oil, natural gas and soil, rocks, minerals. As soon as they have been gotten rid of from a mine or removed it takes a very long time indeed for them to re-form. We have actually counted on fossil fuels for our energy requires because, traditionally, these fuels have actually been reasonably inexpensive, and rewarding for designers. With increasing fuel costs, issues about ecological effect and growing political concerns about oil providers, renewable energy is acquiring in importance. Renewable resources are natural sources that can not be diminished. Examples consist of solar, wind, hydroelectric, biomass and geothermal. Fossil fuels like coal, oil and even clean-burning gas do not exist in unrestricted supply. One day they will be gone. In additional to unending availability, renewable resources create less environmental impact, specifically pollution. Generally speaking renewable resources can be categorized as natural renewable resources and non-organic renewable resources. Plant and animal species are the examples of natural renewable resources whereas gases like oxygen and water are the examples of non-organic renewable resources. Birds or animals getting extinct have now become a regular function. Although some species have actually disappeared from the earth's surface due to natural tragedies, most of them have actually become extinct due to excessive hunting and poaching. Examples of renewable resources are fresh water, fish, and soil. Non-renewable resources such as oil and minerals are irreplaceable, and they do not effectively regrow once they are consumed. Renewable energy describes power created by a renewable source. When the energy is generated, the resource is not exhausted or consumed. They are naturally replenished, and can either be managed so that they last permanently, or their supply is so enormous human beings can never ever meaningfully deplete them. Unlike fossil fuels, renewable energy sources do not release carbon dioxide as a byproduct into the atmosphere. As the quantity of nonrenewable fuel source resources in the world lowers, it is ending up being increasingly essential to discover and make use of alternative fuels. In the US, Alternative Energy is made use of and in general it implies the like renewable, implies any thing besides deriving energy through Fossil Fuel combustion. Alternative energy is likewise a natural deposit ends up being a renewable resource when it is replaced by natural processes at a rate which is quicker than its consumption rate by human beings. Solar radiation, tides, winds and hydroelectricity are the sources which are of lasting accessibility. Renewable resources may include mean products like wood, paper, and leather, if their harvesting is carried out in a sustainable way. So, to summarize, we will certainly just say that renewable resource is a natural resource that can replaced with biological or other natural processes and renewed after a long time. They are part of natural environment however they are threatened by commercial developments and development. Solar radiation, biomass, tides, geothermal, and winds are examples of renewable resources.

Why Alternative Energy Doesn't Offset Fossil Fuel Use
We generally assume that alternative energy production offsets fossil fuel use. But does it? http://GreenIllusions.org Subsidizing energy production expands energy supplies. We like that because it leads to lower energy costs. But, demand for energy subsequently increases. So we come right back to where we started with high demand and so-called insufficient supply. Well then we need more energy subsidies... And the cycle continues. About the book Green Illusions: We don't have an energy crisis. We have a consumption crisis. And this book, which takes aim at cherished assumptions regarding energy, offers refreshingly straight talk about what's wrong with the way we think and talk about the problem. Though we generally believe we can solve environmental problems with more energy—more solar cells, wind turbines, and biofuels—alternative technologies come with their own side effects and limitations. How, for instance, do solar cells cause harm? Why can't engineers solve wind power's biggest obstacle? Why won't contraception solve the problem of overpopulation lying at the heart of our concerns about energy, and what will? This practical, environmentally informed, and lucid book persuasively argues for a change of perspective. If consumption is the problem, as Ozzie Zehner suggests, then we need to shift our focus from suspect alternative energies to improving social and political fundamentals: walkable communities, improved consumption, enlightened governance, and, most notably, women's rights. The dozens of first steps he offers are surprisingly straightforward. For instance, he introduces a simple sticker that promises a greater impact than all of the nation's solar cells. He uncovers why carbon taxes won't solve our energy challenges (and presents two taxes that could). Finally, he explores how future environmentalists will focus on similarly fresh alternatives that are affordable, clean, and can actually improve our well-being.
