These Massive Mirrored Dishes Could Make Solar Cheaper For All | FastCompany
So much sunlight hits the Earth each day that the world’s entire electricity needs could be met by harvesting only 2% of the solar energy in the Sahara Desert. Of course, using solar power as the world’s only energy source hasn’t been possible yet, in part because solar equipment is expensive to make (and getting the power out of the desert would be no easy feat, either). But researchers at IBM think they’re one step closer to making solar universally accessible with a low-cost system that can concentrate the sunlight by 2,000 times.

Next-Gen Photovoltaics Harness Even More of the Sun’s Energy | A Smarter Planet Blog
Photovoltaic cells (the individual units of a solar panel) have been around since the 1970s. But until now, they have not been cost or energy effective enough for widespread adoption as an energy source. IBM Research’s latest foray into solar technology, a second-generation Ultra High Concentrator Photovoltaic (UHCPV) system, converts 30 percent of the sunlight that hits it to Direct Current – versus the 20 percent efficiency of conventional solar panels.

With data, a better way to manage solar and wind energy | SmartPlanet
One of the major challenges of relying on solar and wind as energy sources is their intermittency –- the sun doesn’t always shine and winds don’t always blow.
Since we can’t control the weather, we are coming up with innovative ways to work with it.
