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.

Driving the Future of Renewable Energy: The HyRef technology combines advanced power and weather computer modeling, sophisticated cloud imaging, sky-facing cameras, and on-site sensors to accurately predict solar power and wind energy output and increase the amount of renewable electricity flowing onto grids across the world.

How Weather Science can Help Wind Power Pick Up Momentum | A Smarter Planet Blog
Over the past decade, the use of wind power has exploded–driven initially by demand in North America and Western Europe. But a variety of factors, including the economic slowdown in Europe and low-cost natural gas in the United States, have slowed wind adoption in developed economies. So now the emerging nations are driving growth. Now, aided in part by sophisticated weather science, those countries could play a huge role in blunting the effects of climate change.

World’s first hybrid wind/current generator could generate double the power | Treehugger
Combining a three-bladed Darrieus turbine on top, a Savonius turbine underneath, and a generator in between, the SKWID power generation concept is claimed to be the world’s first hybrid system “capable of maximizing the harvesting of ocean energy from wind and current”.

ElectriCity — Ultramodern Electric Bus Service Launching In Gothenburg In 2015 | Clean Technica
Buses that are silent, energy efficient, and don’t release exhaust — sounds good, doesn’t it? Just such a bus service is now in development in the Swedish city of Gothenburg — it’s currently set to launch in 2015. The new “ultramodern” bus service will be entirely electric and powered entirely by renewable energy sources.

Tuscon Utility Adding 160 Megawatts of Renewable Power 
While some Arizona legislators seem to have a bit of trouble deciphering the U.S. constitution, the state’s utility companies are wide awake when it comes to shifting out of fossil fuels and adopting renewable energy.  Tuscon Electric Power (TEP) has joined the rush to renewables with an announcement that it will purchase the electrical output from solar, landfill gas, and wind installations, which when completed will total almost 160 megawatts or enough to power about 30,000 homes.
The greatest amount will come from ten new solar power installations, which together will account for 107 of the 160 MW.  TEP anticipates completion of these along with the wind and landfill gas projects in 2011 or 2012.
