Fuller believed human societies would soon rely mainly on renewable sources of energy,
such as solar- and wind-derived electricity,. envisioned an age of "universal education and sustenance of all humanity".
"The heart has reasons that reason does not understand."
The value of solar and wind decline in economic value as they become larger shares of the electricity grid for physical reasons. They produce too much energy when societies don't need it and not enough energy when they do.
Electricity is derived from many non-renewable energy sources like oil, natural gas and coal.
In reality, Republicans have long been at war with clean energy. They have ridiculed investments in solar and wind power, bashed energy-efficiency standards, attacked state moves to promote renewable energy and championed laws that would enshrine taxpayer subsidies for fossil fuels while stripping them from wind and solar.
Clubbing energy efficiency with renewable energy will give us the much-needed window to incubate the renewable energy sector, particularly large solar, without having to increase the price of electricity.
The sunlight ... that strikes Earth’s land surface in two hours is equivalent to total human energy use in a year. While much of that sunlight becomes heat, solar energy is also responsible for the energy embodied in wind, hydro, wave, and biomass, each with the potential to be harnessed for human use. Only a small portion of that enormous daily, renewable flux of energy will ever be needed by humanity.
By the year 2000, such renewable energy sources could provide 40 percent of the global energy budget; by 2025, humanity could obtain 75 percent of its energy from solar resources.
I think there's a really great amount of potential for Hawaii to become an example of what's possible with renewable energy because there are so many renewable resources here: energy, solar energy, and wind energy. There's so much potential here.
We are already witnessing a transformation in the U.S. economy to increased production of lower carbon energy through fuel switching to natural gas and expansion of wind, solar, geothermal, and other renewable non-carbon intensive energy sources.
There is an urgent need to stop subsidizing the fossil fuel industry, dramatically reduce wasted energy, and significantly shift our power supplies from oil, coal, and natural gas to wind, solar, geothermal, and other renewable energy sources.
I strongly agree with Vice President Gore that we cannot drill our way to energy independence, but must fast-track investments in renewable sources of energy like solar power, wind power and advanced biofuels...
One of the reasons I think the population question is important, if we want to be as green as possible, any of our energy that is truly renewable is limited. Solar and wind are intermittent and they're so diffuse, it's difficult to harness them in a significant way. But one thing we could be doing is making it a law (like it is in Israel and Cyprus) to take every building eight stories or under and heat all of the water in those buildings with solar energy. It's absolutely simple and cheap technology.
Even though I love solar and love wind, like most people do, I like the renewable sources, they alone are not going to get America energy independent.
We need a national renewable energy goal. Such a goal, sometimes called a renewable energy standard (RES), would spell out what percentage of our power America plans to get from renewable sources.
We've offered direct financial support for a range of renewable energy sources, whether it be large-scale solar, whether it be geothermal, whether it be wave power or wind power.
Rely on renewable energy flows that are always there whether we use them or not, such as, sun, wind and vegetation: on energy income, not depletable energy capital.
The potential for alternative energy sources, mainly solar and wind power, to completely replace coal and gas for utility generation globally is, I think, certain. The question is only whether it takes 30 years or 70 years.
