Sometimes it seems like a new week, a new cell record achieved.
A new solar cell is pushing the boundaries of what was thought possible for normal, direct sunlight.

Hot new solar cell
System converts solar heat into usable light, increasing device’s overall efficiency.
A team of MIT researchers has for the first time demonstrated a device based on a method that enables solar cells to break through a theoretically predicted ceiling on how much sunlight they can convert into electricity

Santa Monica is following San Francisco with a rooftop ‪‎solar‬ requirement for all new construction — both residential and commercial. Dean Kubani, Santa Monica’s sustainability manager, said solar energy is "imperative if we are to protect our kids and grandkids from the worst effects of climate change." Read my Inhabitat story for more.
Exactly one week after San Francisco became the largest U.S. city to require rooftop solar installations on new buildings, Santa Monica followed with similar legislation. On April 26, the Santa Monica City Council approved an ordinance requiring rooftop solar systems for all new construction -- both residential and commercial.

Under the best circumstances utility scale solar costs just $34 / MWh ($0.034 / kWh), and will likely drop to $0.02 / kWh by 2020. This is really cheap, but of course it's intermittent, available just ~8 hours a day. On the other hand, we can use intermittent, cheap electricity to desalinate water, produce synthetic gasoline, or smelt aluminium.

More space to soak up the sun
Hundred-metre long platforms which remain steady and stable in rough sea weather: TU Wien’s lightweight construction creates new space for solar energy out on the water.
This new construction allows areas the size of football fields to be made available on the water with ease. The research team at TU Wien has developed concepts for harnessing the sun over the water using photovoltaics and parabolically shaped mirrored troughs, with many

When will you go solar thermal?

Solar thermal energy systems may transfer more than 90% of the sun's energy into hearing or cooling. These systems are 6-8 times more efficient than solar cells and at a cost of only 0.05 € or 0.014 US$ for each BTU.
The emission is only 3 gram for each kWh or 0.88 gram for each BTU.

Why solar thermal energy systems may be the planet's lifejacket

What is our energy needs?
All over the world, energy efficiency requirements has turned the actual energy consumption to less needs for electricity. This is because all manufacturers of light bulbs, PC's, TV's, freezers, refrigerators, ovens and other appliances has successfully been certified with energy labels that tells the users how much energy they may save by selecting the right equipment. Consequently, our need for energy that drivers these apparatuses is decreasing rapidly.
That is not the case for heating, cooling and hot water demands. While new apparatuses is considered a status and a better lifestyle, so is the trend towards more fancy bathrooms with tropic showers and bigger bathtubs and our seeking for better and more comfortable homes with generally higher indoors temperature during the cold season and generally colder temperature during the warm season. All of which increases our heating and cooling demands dramatically.

What is solar thermal?
Solar thermal energy is a conversion of the solar energy in the Ultraviolet , Visible and near Infrared spectrum of the solar energy. Some of the technologies present on the market already, may utilize as much as 90% of the Sun's constant irradiation at the Earth's surface. This means that between 1,000 and 200 Watt's are converted into heat depending on your location and time of the year. Solar cells, on the other hand, only harvest in the visible spectrum and this is why:

1) The energy efficiency is up to 90% for solar thermal opposed to ≈ 15% for solar cells.

2) Cost of solar thermal is 0.05 € per kWh opposed to solar cells at 0.22 € per kWh. In imperial units 204 USD per BTU for solar thermal opposed to 853 USD per BTU for solar cells

3) The CO2-emission for solar thermal is at 3 grams per kWh opposed to 28 grams for solar cells. In imperial units 22 lb per BTU for solar thermal opposed to 210 lb per BTU for solar cells.

The benefits of solar thermal
Solar thermal energy is locally produced hot water that can be used to heat up your building and hot water supply or as cooling of buildings.
You will usually have your money back within 4 years and the installations will last for more than 30 years.

-No grid needed
-Minimized CO2-footprint
-Easy installation
-Low or no maintenance
-No more heavy energy bills
