Devices called ultracapacitors have recently become attractive forms of energy storage: They recharge in seconds, have very long lifespans, work with close to 100 percent efficiency, and are much lighter and less volatile than batteries. But they suffer from low energy-storage capacity and other drawbacks, meaning they mostly serve as backup power sources for things like electric cars, renewable energy technologies, and consumer devices.

A company named SolarWindow Technologies has created transparent solar panels, which turn regular windows into photovoltaics 50 times more productive than the ones you’d attach to a roof.?

ALBANY, N.Y. (NEWS10) – New York Governor Andrew Cuomo announced the New York State Public Service Commission’s approval of New York’s Clean Energy Standard on Monday.

Scientists from the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have discovered a possible secret to dramatically boosting the efficiency of perovskite solar cells hidden in the nanoscale peaks and valleys of the crystalline material.

The Environmental Protection Agency’s “Clean Power Plan” unleashed a firestorm of criticism — but New York has been well ahead of the debate by setting out the most ambitious environmental targets in the country. In fact, Governor Andrew Cuomo has staked his reputation on achieving “50 by 30,” meaning that by 2030 the state would get half of its electricity from renewable energy sources. This is a bold but achievable goal. If it were embraced by today’s presidential candidates and then embraced nationally, the United States would make a huge contribution to preventing climate change.

“If” is the key word, unfortunately.

The energy world is full of complicated technologies and regulations, usually expressed in a thicket of off-putting acronyms. It's enough to make your brain hurt.

So today, let's look at something simple.

SolarCity Corp. and two other solar developers joined some of New York’s largest utilities in a proposal to phase out a state program that lets owners of rooftop power systems sell electricity back to local utilities at retail prices.
