Tower of Power

read
Is concentrated solar power the future of renewable energy? A Guardian video shines a light on the world's first commercial solar tower.

For most of us, the vision of a solar-powered future conjures a mental image of rooftops covered in photovoltaic panels. But PV tech is actually only a few decades old, and humans have been harnessing the sun's power for millenia. Concentrated solar power (CSP), or "solar thermal," is an ancient, low-tech version of solar energy capture, in which the sun's heat energy is used to boil water and......read more

Low Cost Solar Paint?

read
NextGen solar’s nanoscale solar paint to provide cheap and efficient solar power.

For all the excitement over low cost solar power, much of it is still in the development stage backed by government resources and has yet to prove that it can compete on the market with cheap fossil fuels. However some private investors are starting to bet on low cost solar in a big way. Among them is tech specialist Len Batterson, whose startup NextGen Solar is kicking into gear. NextGen......read more

Solar Power, On The Cheap

read
Five ways to harness the energy of the sun—for less than $500.

Damn you, solar energy. How badly we want you to power our homes. How clearly we don't have the tens of thousands of dollars we need to make it happen. Renewable, abundant solar energy may power the future but for now, only green-minded millionaires can afford it. Or so we thought. In fact, Photovoltaic panels are getting smaller, cheaper, and more efficient. Installation costs are declining......read more

Nipton, California taps the sun for its energy needs.

A small town on the border of the Mojave Desert is the new leader in solar energy. Nipton, California, a town of about 250 people, gets 85% of its electricity from a new 80 kilowatt solar project. This proves that renewable energy technology is already advanced enough to power our homes and lives, albeit maybe just in small towns for now. But the possibilities are endless, and as a gateway......read more

A U.S. military base goes solar.

On the Camp Lejeune Marine Corps base in North Carolina, families are turning to solar panels to heat the water in their homes. Eventually, 900 homes on the military base will have the shiny reflective panels on the roof. By transfering heat via pipes to a water tank that reaches temperatures of 180 degrees fahrenheit, the solar panels can heat around 75% of the water used by families living on......read more
