The World's Best Solar Power Regions are the Coldest Locales

Large expanses of desert have received most of the attention when it comes to large solar power installations, but a new study published in Environmental Science & Technology says that the world's coldest regions are actually some of wow look it purchase levitra in canada the best places for solar power generation.

The study found that the Himalaya Mountains, the Andes and follow link discount cialis Antarctica are some of the most ideal solar power locations, with the ability to produce more energy per hectare than the usefull link best prices on brand levitra world's deserts.  The Himalayas could provide power to China, while the polar regions see 24 hours of sunlight a day for half the year.

The study used weather data to account for any decrease in solar cell output due to freezing temperatures, snow fall and transmission losses when calculating the areas' power generation potential.

Research bases on Antarctica already successfully make use of solar and wind power for electricity, but transmitting power generated at the poles or deep in the Himalayas to towns and cities will likely prove to be the biggest hurdle to these solar power "hot spots."

Dow Solar Shingles Finally Hitting U.S. Markets

We wrote about the best online cialis lovely solar roof shingles introduced by Dow Solar a couple of years ago and now they're finally going to be available to cialis low priced the masses.  The solar shingles look amazingly like traditional roof shingles and fully replace traditional shingles on the home while generating electricity.

The shingles use thin-film solar cells, which are less efficient than the silicon cells in conventional solar panels, but actually much more durable.  The first state where these shingles will be widely available is Colorado, with large quantities coming to a dozen other states by the end of 2012.

The solar roof shingles have an efficiency of about 10 percent, but if you cover your whole roof in them, you're still looking at a nice power pay-off.  Another bonus is that solar panels of any type keep areas under where they're installed cooler, which means you'll need less electricity for cooling anyways.

Dow has partnered with major home building company D.R. Horton to build homes outfitted three kilowatts of their solar shingles.  The homes will be large ones -- ranging from 2,205 to 4,115 square feet -- and will start at $485,950.  On the green jobs front, Dow is building these shingles in a Midland, Michigan plant and says the facility will create 1,275 jobs by 2015.

Sky-scraping Tower Will Power 100,000 Homes with Hot Air

A 2,600-foot tower planned for the Arizona desert will be the world's second tallest structure and will be able to power 100,000 homes through hot air alone.

The solar updraft tower, designed by EnviroMission, will work by collecting hot air as it rises from the heated ground surrounding it.  The very tall, narrow tower increases the wow look it online pharmacy cialis strength of the hot air flowing upward, where it will turn 32 turbines along the way.

The tower will be able to produce 200 MW of electricity each day and, unlike solar power technologies, will be able to produce electricity at night too since heat from the ground will still be flowing upward and it will operate without the use of water.

This technology comes at a pretty steep price -- $750 million to build -- but since hot air is free, the operating costs going forward will be very minimal and the tower should last at least 80 years.

The tower will be made of concrete, which is drug impotence levitra a very carbon-heavy material, but the clean energy produced by the tower should cancel out the carbon emissions of making it within 2.5 years.

Germany Covers Old Pit Mine with World's Largest Solar Park

A new section added onto a huge solar park in Eastern Germany now makes it the largest solar park in the world, but the more interesting fact about this section is that it was built over an old pit mine that had rendered that land useless for years.

The new section added 78 MW to the plant and, amazingly, it was constructed in just three months.

Using land that is otherwise undesirable is a great tactic for large solar developers because not only are they turning the it's great! generic levitra india remnants of something that once harmed the environment into an energy plant that is far gentler to it, but it also ensures that there isn't competition for that land for food production or other important uses.

The German solar park near Senftenburg now has a capacity of 166 MW.

Google Puts Up $75 Million for Residential Solar Installations

Google has set up a $75 million fund that will pay for about 3,000 residential solar installations in California, Colorado and Arizona.  The fund will be overseen by Clean Power Finance who will work with installers to offer financing options to homeowners.

The fund will allow homeowners who want to incorporate solar power in their homes, but can't afford the high upfront costs of a solar power system, to enter into lease agreements or power purchase agreements with the installers.

This fund is the second for Google, who also created a $280 million residential solar fund that California-based SolarCity will administer.  That fund will be overseeing installations, lease agreements and power purchase agreements in 11 states and Washington, D.C.

The popularity of viagra canadian residential and small scale solar is at a high because of the federal and state tax incentives for homeowners.  Companies who invest in these projects (i.e. Google), get large tax credits as well.
