Renewable energy is energy generated from natural resources — such as sunlight, wind, rain, tides and geothermal heat — which are renewable (naturally replenished). Renewable energy technologies include solar power, wind power, hydroelectricity, micro hydro, biomass and biofuels.

- There is one forecast of which you can already be sure: someday renewable energy will be the only way for people to satisfy their energy needs. Because of the physical, ecological and (therefore) social limits to nuclear and fossil energy use, ultimately nobody will be able to circumvent renewable energy as the solution, even if it turns out to be everybody’s last remaining choice. The question keeping everyone in suspense, however, is whether we shall succeed in making this radical change of energy platforms happen early enough to spare the world irreversible ecological mutilation and political and economic catastrophe.

- More solar energy falls on Earth in one hour than all the energy our civilization consumes in an entire year. If we could harness a tiny fraction of the available solar and wind power, we could supply all our energy needs forever, and without adding any carbon to the atmosphere.
- Every percentage point increase in homegrown renewable energy makes us that much more energy secure. The progress in electricity is encouraging, but growth is not yet strong enough in renewable heat and transport to meet the government's objectives.

- If you told me that innovation had been frozen and we just have today's technologies, will the world run the climate change experiment? You bet we will. We will not deny India coal plants; we will run the scary experiment of heating up the atmosphere and seeing what happens. The only reason I'm optimistic about this problem is because of innovation. . . . I want to tilt the odds in our favor by driving innovation at an unnaturally high pace, or more than its current business-as-usual course. I see that as the only thing. I want to call up India someday and say, "Here's a source of energy that is cheaper than your coal plants, and by the way, from a global pollution and local pollution point of view, it's also better."

- Cheaper coal and cheaper gas will not derail the transformation and decarbonisation of the world’s power systems. By 2040, zero-emission energy sources will make up 60% of installed capacity.

- We have long supported a carbon tax as the best policy of those being considered. Replacing the hodge-podge of current, largely ineffective regulations with a revenue-neutral carbon tax would ensure a uniform and predictable cost of carbon across the economy. It would allow market forces to drive solutions. It would maximize transparency, reduce administrative complexity, promote global participation and easily adjust to future developments in our understanding of climate science as well as the policy consequences of these actions.
- [W]ind and solar power have been rapidly winning market acceptance. Last year, the installed capacity of solar power in the United States nearly doubled. And wind is now being harnessed to produce 5.5 percent of America’s electricity, according to the U.S. Energy Information Administration.
