What we're learning is that the sun and its warmth isn't the only way to get warmth in the solar system, and we've been thinking that for some time.
Solar power, wind power, the way forward is to collaborate with nature - it's the only way we are going to get to the other end of the 21st century.
Even if you don't care about the environment whatsoever, solar panels are really cool, and are an investment because they save money in the long run.
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.
Battering down solar cells on the roofs of Wal-Marts in California. I think that will be some of the highest-return investments that anyone ever makes.
The green appeal of solar sailing - traveling by light, once chemical propellants have done their dirty job of orbital insertion - ought to be powerful.
Among the plausible niches for extraterrestrial life in our solar system, the clouds of Venus are among the most accessible and the least well explained.
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.
I have no doubt that we will be successful in harnessing the sun's energy. If sunbeams were weapons of war, we would have had solar energy centuries ago.
I'd love to go into space again if there were a mission to Mars. I'd also love to go to a completely different planetary system, out of our solar system.
Solar power - the costs have dramatically fallen, far faster than anyone has speculated. It's probably one of the greatest steps forward in human history.
Water-based life is very much an Earth-centric view, and we can push the envelope on that here in our own solar system. We have the methane seas of Titan.
Once you got a solar panel on a roof, energy is free. Once we convert our entire electricity grid to green and renewable energy, cost of living goes down.
I drive a hybrid, and we've changed our light bulbs and windows and installed solar panels and geothermal ground source heat pumps and most everything else.
Only nuclear can lift all humans out of poverty while saving the natural environment. Nothing else - not coal, not solar, not geo-engineering - can do that.
Saudi Arabia is blessed with energy from various sources, whether it's fossil in oil and gas, or renewables, wind and solar, that are extremely competitive.
Small bodies in our solar system, like comets and asteroids, help us understand how the solar system formed and provide opportunities to advance exploration.
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.
We live in a world bathed in 5,000 times more energy than we consume as a species in the year, in the form of solar energy. It's just not in usable form yet.
We need to focus on green jobs: solar, wind, geothermal, biomass. There's so many opportunities. But other countries like China are getting ahead of the curve.
I am not a scientist. I have never analyzed the far reaches of the solar system through the lens of a telescope nor scrutinized cancer cells under a microscope.
Climate changes are caused by solar radiation and other natural phenomena, so I don't worry one bit about that. Nothing we do can change anything in the climate.
The renewable industry claims technical innovations will improve solar and wind - but in reality nothing can change the lower power density of sunlight and wind.
I was employed at the Solar Energy Research Institute in the late '70s when Carter was president, and as a country, we had a goal of renewable energy development.
You have to work with the auto industry, the oil companies, you have to work to develop renewable fuel, whether it's solar or different kinds of fuel or whatever.
Fossil fuels are raw materials that have to be extracted and processed. Wind and solar energy are different. The only costs associated with them are technological.
Because Alpha Centauri is so close, it is our first stop outside our solar system. There's almost certain to be small, rocky planets around Alpha Centauri A and B.
Hydro, wind, solar, and biomass energy have economic impact across the state and, with collaboration and focus, can become engines of prosperity for more Georgians.
Tribes have the potential to provide almost 15 percent of the country's electricity with wind power, and have 4.5 times the solar resources to power the entire U.S.
Windmills and solar cells are carbon-free sources of electricity. But they are costly. If you've been investing in those, give it up. That game is effectively over.
All organizations start with a structure that looks like a dynamic solar system. They can be very fast, agile. They attract people who play around with crazy ideas.
I've got an electric little motorcycle that I go to the supermarket with every day, and it's powered by the solar panels, so it's really got a zero carbon footprint.
When you look at Venus and the Earth, they formed at about the same place in the solar system. They're made of about the same materials; they're about the same size.
If we just isolate distributed solar all by itself, it does not work without the utility around it. And so the utility needs to be paid for the services it provides.
Titan is Saturn's largest moon, and, until Cassini had arrived, there was the largest single expanse of unexplored terrain that we had remaining in our solar system.
In Congress, I've advocated for an all-of-the-above energy policy that identifies and promotes alternative energy sources such as wind, solar, biomass and hydropower.
Bringing solar as a renewable energy resource for those who are not able to install solar panels on their roofs allows more communities to benefit from a solar array.
Sunspots are hubs of intense magnetic activity and they trigger solar flares that launch charged particles, X-rays, ultraviolet radiation and radio waves at the Earth.
India is a good example of a country that has embarked into wind and solar energy production and creating jobs in it. Other countries can learn from India's experience.
Homeowners want solar power. It's cost-effective. We invented a business model that makes it really easy for consumers to switch to solar - and that's solar-as-a-service.
The planets and moons of our solar system are blatantly visible because they reflect sunlight. Without the nearby Sun, these planets would be cryptic and dark on the sky.
Even if we didn't have greenhouse gases, were going to have to move away from fossil fuels, as we're going to run out. They're finite, whereas solar and wind are infinite.
