A Quote by Ray Kurzweil
We only have to capture 1/10,000th of the solar energy landing on earth to completely satisfy all our energy needs.

If we continue to develop our space program we can take solar energy and convert it to electrical energy by beaming it back to earth.
The transition from coal, oil, and gas to wind, solar, and geothermal energy is well under way. In the old economy, energy was produced by burning something - oil, coal, or natural gas - leading to the carbon emissions that have come to define our economy. The new energy economy harnesses the energy in wind, the energy coming from the sun, and heat from within the earth itself.
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.
The rain-cum-solar energy centre functioning in Chennai is a source of credible public information on rainwater harvesting and solar energy use. Such centres need to be replicated in all our cities, towns and block headquarters.
The radiations that pour upon the earth cause the biosphere to take on properties unknown to lifeless planetary surfaces, and thus transform the face of the earth. Activated by radiation, the matter of the biosphere collects and redistributes solar energy, and converts it ultimately into free energy capable of doing work on earth.
If you ask me, it'd be a little short of disastrous for us to discover a source of clean, cheap, abundant energy because of what we would do with it. We ought to be looking for energy sources that are adequate for our needs, but that won't give us the excesses of concentrated energy with which we could do mischief to the earth or to each other.
Replacing traditional sources of energy completely with renewable energy is going to be a challenging task. However, by adding renewable energy to the grid and gradually increasing its contribution, we can realistically expect a future that is powered completely by green energy.
We need to bring sustainable energy to every corner of the globe with technologies like solar energy mini-grids, solar powered lights, and wind turbines.
As someone who runs a solar financing company and founded the world's largest youth clean energy organization, I know solar energy is a very good investment.
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.
Huge advances in clean energy technology are happening all the time. Solar and wind are booming. New ways to generate energy from our windows, the paint on our walls, and even our bike paths are being invented all the time. Technology is moving forward, but it needs to be moving forward faster.
Men are weak now, and yet they transform the Earth's surface. In millions of years their might will increase to the extent that they will change the surface of the Earth, its oceans, the atmosphere, and themselves. They will control the climate and the Solar System just as they control the Earth. They will travel beyond the limits of our planetary system; they will reach other Suns, and use their fresh energy instead of the energy of their dying luminary.
This curious faith is predicated on the notion that we will soon develop unlimited new sources of energy: domestic oil fields, shale oil, gasified coal, nuclear power, solar energy, and so on. This is fantastical because the basic cause of the energy crisis is not scarcity: it is moral ignorance and weakness of character. We don't know how to use energy or what to use it for. And we cannot restrain ourselves. Our time is characterized as much by the abuse and waste of human energy as it is by the abuse and waste of fossil fuel energy.
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.
If we are serious about moving toward energy independence in a cost-effective way, we should invest in solar energy. If we are serious about cutting air and water pollution and reducing greenhouse gas emissions, we should invest in solar energy.
I've been very passionate about renewable energy for many years, particularly solar energy and its capacity to bring abundant clean, sustainable energy to millions around the globe.
