Despite the continued financial crisis, falling solar prices around the world, good government subsidies (particularly in Germany and Italy), and an interest in addressing accelerated climate change helped to make 2010 such a successful year for the solar photovoltaic industry.
Cumulative solar capacity is now at 40 GW, 70% higher than the 23 GW it was at at the end of 2009.
Europe, alone, added about 13 GW of new solar power installations in 2010. Clearly, leading the world. Feed-in tariff programs in Germany and Italy, where nearly 7 GW and approximately 3 GW were added, respectively, were a major driver of 2010′s growth.
“Solar PV is continuing to develop in countries that put a feed-in tariff in place,” said EPIA economist Gaetan Masson.
Other than Germany and Italy, other countries with significant solar power growth were:
•the Czech Republic (1.3 GW)
•Japan (1 GW)
•United States (0.8 GW)
•France (0.5 GW)
•China (0.4 GW)
“Solar panel prices have halved since 2007, say analysts, at about $1.8 per watt at the end of 2010 compared with $3.7 three years earlier,” Reuters reports.

Walking around on the Mobile World Congress 2011, they are hard to miss: e Umeox Apollo, an Android smartphone with a green edge–it runs on solar power!
It’s not just the solar power that makes this one notable, either; it’s running Android 2.2, it’s got a built-in flashlight, a rear-facing camera of as yet unannounced resolution, a 3.2 inch touch screen display, a MediaTek processor, and a microSD card slot for adding storage.
And though it sounds a bit slack in terms of features, one thing that will impress is its low price. Word has already emerged suggesting that this one will go for $100, off contract. Getting a contract with this one will likely drop the price through the floor, possibly even into the free category.
Naturally, this one’s no iPhone killer. Maybe if you got it real drunk, told it the iPhone was sleeping with its girlfriend and then gave it a gun it might, but on its own, there’s no way these two would even play in the same ballpark. A lot of the features you might be hoping for–HD video, plenty of room for pictures and songs in the media player…frankly, I’d be surprised to find Android Marketplace was available on this one–will probably not be found here. But if you’re gearing yourself more toward the basics, I’d say this one could probably do a lot of people a lot of good.
Still though, it’s not the first green item to come out of MWC, and so we’ll have to keep a close eye on what all’s going on in that vein. We might be looking at the start of a real trend here–the eco-friendly mobile hardware trend–and it’ll be things like the Umeox Apollo that drive it.

Almost all of the world’s demand for energy for electricity, transportation and heating could be met from renewable sources such as wind, solar and geothermal power by 2050, WWF International said.
The share of oil, coal, gas and nuclear power in the global energy mix could be whittled down to 5 percent over the next four decades, WWF said today in an e-mailed report produced with researchers at Dutch organizations Ecofys and the Office for Metropolitan Architecture. Energy saving measures can cut total demand by 15 percent from 2005 levels even as the population, industrial output, freight and passenger travel rise, they said.

The project will cost about $100,000, but qualified for a 30 percent tax credit from the federal government, the report said. It will generate between 5 and 10 percent of the building's energy needs. Alaska, we salute you!

A town in The Netherlands will soon become home to a solar cycling path which it is hoped could pave the way for a new source of sustainable energy.
Called SolaRoad, the project in the town of Krommenie, around 10 kilometres to the northwest of Amsterdam, is backed by the Province of North Holland, construction firm Ooms Avenhorn Group, research group TNO and technology business Imtech, and essentially sees the standard road surface replaced by solar panels.
The cycle path being used to pilot the scheme will have between 1.5 and 2.5 metres of concrete base, with a tough glass surface, underneath which will be a 1 centimetre layer of crystalline silicon solar cells, reports the website Green Blorge, which adds that the surface will be tough enough to withstand the force of a lorry being driven over it.
The website adds that the group developing the concept believe that the cycle path should generate 50 kWh per square meter annually. ICT systems will allow electricity to be distributed during peak sunshine hours as well as at night and during cloudy conditions.
It is hoped that eventually the concept could be rolled out across the 137,000km road network in the Netherlands, providing power for everything from traffic signals and street lights to nearby homes.
In response to concerns expressed in the comments below regarding the possibility of cyclists slipping on the surface, particularly during wet conditions, a spokesman for one of teh project's partners, TNO, told road.cc: "The safety and comfort of the future users of the SolaRoad is an important requirement in the technical development.
"In the current prototype the glass surface is treated to create a roughness, which gives sufficient skid resistance for a safe use of the road, both in dry and wet conditions. We are currently testing the durability of the roughness and skid resistance and will make improvements when and where necessary."
