Broader definitions of the sharing economy include peer-to-peer lending or putting a solar panel on your roof and selling power back to the gr/d ( 电网)

Premier Gardens is one of a half-dozen subdivisions in California where every home cuts power consumption by 50%, mostly by using low-power appliances and solar panels.

But inside, special windows cut power bills by blocking solar heat in summer and retaining indoor warmth in winter

The rest of the energy savings comes from the solar units.

Solar homes produce the most power on the hot sunny afternoons when everyone rushes home to turn up the air conditioner

It helps us lower usage at peak power times," says solar expert Mike Keesee.

Tom said he would come to repair our solar heater when he has time.

Already there are many alternative fuel vehicles on the market, powered by anything from solar power to natural gas.

They are more cost-effective than vehicles powered by solar energy

As solar panels get cheaper, the world is likely to see more skyscrapers covered in solar panels, collecting energy much like trees do.

Called "the Wattway," the roads will be built through joint efforts with the French road-building company Colas and the National Institute of Solar Energy.

During this renovation the building's owners, CIS, consulted the solar panel company, Solarcentury.

France isn't the first country to kick around the idea of paving its roads with solar panels.

Imagine a world where building the tallest skyscraper wasn't a race of height, but rather one to collect the most solar energy.

In 2004, the completed CIS tower became Europe's largest collection of vertical solar panels.

In November 2015, the Netherlands completed a 229-foot-long bike path paved with solar panels as a test for future projects.

Last week, France announced that the country will pave 621 miles of road with solar panels over the next five years, with the goal of providing cheap, renewable energy to five million people.

The company spent the last five years developing solar panels that are only about a quarter of an inch thick and are strong enough to stand up to heavy highway traffic without breaking or making the roads more slippery.

Technological innovations have unleashed the power of renewables such as wind, hydro, solar, and geothermal .

Advanced batteries are moving out of specialized markets and creeping into the mainstream, signaling a tipping point for forward-looking technologies such as electric cars and rooftop solar panels.

That’s energy in all forms--oil, gas, coal, nuclear, solar and even wind power.

They will serve as modem Magellans, mapping out the solar system for whatever explorers follow, whether man or machine.

But while much of the research and innovation has concentrated on finding less-polluting energy alternatives, it may be decades before clean technologies like wind and solar meet a significant portion of our energy needs.

Kasselman wants to build an array of solar magnifying mirrors at one end of the line to collect and focus heat onto water-filled tubes.

Technological innovations have unleashed the power of renewables such as wind, hydro, solar, and geothermal (地热).

A build-it-yourself solar still is one of the best ways to obtain drinking water in areas where the liquid is not readily available.

His not-for-profit organization runs 100 river boats that serve as floating libraries, schools, and health clinics, and are equipped with solar panels and other communicating facilities.

The solar still works by creating a greenhouse under the plastic.

When a solar still works, drops of water come into the cup form beneath the sheet.

But increasingly the story is about the plummeting prices of renewables, especially wind and solar.

In March, for the first time, wind and solar power accounted for more than 10 percent of the power generated in the US, reported the US Energy Information Administration.

The cost of solar panels has dropped by 80 percent and the cost of wind turbines by close to one-third in the past eight years.

While fossil fuels – coal, oil, gas – still generate roughly 85 percent of the world's energy supply, it's clearer than ever that the future belongs to renewable sources such as wind and solar.
