400 MW Solar Farm Coming to Southeast


As sunny as the southeastern U.S. is, solar power development hasn't taken off as quickly as you'd think.  That will change dramatically when a new 400 MW solar farm is built in one of three states:  Florida, Georgia or North Carolina.  The huge project could potentially be the world's largest when it's completed.  The current largest is an 80 MW solar plant in Ontario, Canada, but many large projects are in the planning or construction stages.

The project, being developed by National Solar Power, will consist of 20, 200-acre solar farms each with a capacity of 20 MW.  The panels will be seven feet tall or less and surrounded by vegetation to help them blend into the landscape.  The project will be able to power about 32,000 homes.

The areas that are being considered for the huge solar project are Gadsden, Hardee, Osceola and Suwannee counties in Florida, Sumter and Tatnall counties in Georgia, and Guilford County in North Carolina.  National Solar Power is weighing factors like amount of undeveloped land, economic development and tax incentives, community support and access to a qualified workforce.

The project will create 400 jobs during its five-year construction and about 120 permanent jobs.  The decision of where it will be built should be made by the end of the month.

DOE Backs Installation of 733 MW of Solar Panels on Industrial Rooftops

The Department of Energy is providing backing for a $1.4 billion loan for Project Amp, a plan to install 733 megawatts of photovoltaic (PV) solar panels on industrial buildings in 28 states and the District of Columbia. This is nearly equal to the entire amount of PV installed in the US in 2010. The project is expected to lead to the creation of one thousand new jobs and is expected to last for four years.

When complete, Project Amp is expected to produce up to one million megawatt hours annually. The power that is produced is not going to be used on site necessarily, but will instead be fed to the grid to add more solar power to the available production.

New Map Shows NYC Could Double Nation's Solar Capacity with Rooftop Arrays


A new map created by the City University of New York and the Department of Energy shows that two-thirds of the New York City's rooftops are suitable for solar power installations and if all of those roofs were outfitted with solar panels, the city could double the nation's current solar power capacity.

The NYC Solar Map was made by surveying every -- yes every -- rooftop in the city to see which were most primed for capturing solar power.  A team of researchers made a series of flights over the city using a Lidar laser system to collect date on size, shape, angle and sun exposure vs. shade cover of each building.  The rooftops that were deemed suitable could generate 5,847 MW, which is more than twice the nation's capacity of 2,300 MW, and enough to power half the city on solar power alone.

The map is interactive and allows users to type in addresses and get information on any building's solar potential.  Building owners can even draw a mock system on their roof and see how much energy it would generate and how much money it would save.  The map also has full details on all existing rooftop installations.

One Million Solar-Powered Homes in Bangladesh


Bangladeshi officials have announced that there are now over one million homes powered by solar energy in the country.  In a flurry of expansion, Bangladesh went from 7,000 solar-powered homes in 2002 to the one million mark only 9 years later.

The reason solar power has caught on so quickly there is that most rural homes are off the electricity grid and renewable energy is the easiest way to for those people to get access to power.  Approximately 60 percent of the population doesn't have access to reliable electricity, so non-governmental organizations have been working in the country to provide low-cost loans for solar panel installations.

The country hit the one million milestone 18 months ahead of schedule and officials believe that there will be 2.5 million solar-powered homes by 2015.

Triple Threat: New Generator Harnesses Energy from Sun, Wind and Rain


One thing that's known for sure about the future of renewable energy is that it will take all types to fulfill our energy needs.  The wind isn't always blowing and the sun isn't always shining, but if wind, solar, geothermal, wave/tidal and any other type of renewable energy generation are all utilized and all feeding the grid, then we'll be more than covered.  But what about devices that can harness more than one of these renewable energy sources at once?

A new renewable energy generator developed by researchers at the University of Bolton in the UK is able to harness energy from not one, but three sources:  sunlight, wind and rain.  I'm sure you're imagining one crazy-looking contraption, but this new technology actually uses ribbons of piezoelectric polymer that are coated with a thin, flexible solar PV film.

The ribbons generate electricity anytime they're disturbed, whether by wind or rain drops, or when the sun is shining.  The more forcefully they're moved, the greater the energy payoff.  The researchers imagine a pine cone shaped structure consisting of thousands of these ribbons.

The ribbons can only generate small amounts of electricity, so the researchers foresee them being used in low energy applications like powering gadgets.  Another possibility is applying the same techniques to nylon for use in energy-generating clothing.
