It is part of the National Plan for Islands Protection to use marine renewable energy to improve the sustainability of remote islands.
One reason that offshore wind has not caught on in the United States is the steep cost of erecting a tower in the water, but researchers at the University of Maine tried another approach on Friday by launching a floating wind machine. It is the first offshore wind installation in United States waters, according to the Energy Department, which helped pay for it. The tower, launched in Brewer, Me., sits on three hollow concrete tubes and will be anchored in the Gulf of Maine. It is a mere 20 kilowatts in capacity, an amount of power that could be soaked up by a handful of big suburban houses on a hot summer day. But it is one-eighth the dimensions of the one the researchers hope to deploy in the next few years, a gigantic 6-megawatt model, with each blade as long as the wingspan of a Boeing 747. Because of its location, it will have two big advantages over machines on land, according to Habib J. Dagher, a professor of civil engineering at the university. Onshore wind machines produce most of their energy at night, when it is least valuable to utilities buying the power, but this one will catch the predictable, strong breezes that come up every sunny summer afternoon, he said, when the sun heats the land more than the sea, creating an onshore breeze.

We need to do what has been done many times before in human history at key tipping points - embrace change and do what must be done - move strongly toward a renewable and sustainable energy future. It is, in my opinion, the fastest, best and the cheapest way to get there.
Solar market growth slowed in 2012, after setting a record pace in 2011. While the market stabilized solar is still becoming a larger source of power generation, expected to surpass 100 GW of cumulative installed capacity globally this year.
Installing a white reflective "Cool Roof" coating is an inexpensive solution to extend the existing roof service life and synchronize the roof with the solar array service life.
Our Combined Heat and Power (CHP) solar module provides up to 4 times more energy output (thermal and electric power) than any standard photovoltaic module.
All though there could be huge advantages to directly extracting carbon dioxide from our atmosphere instead of from its source, there has been very little R&D funding to explore and make it a reality. By beginning the process of recycling CO2, America would be building the technology now for a sustainable hydrocarbon future.
Water management spurred by scarcity in the US is likely to produce new financing and business models, technological innovation and greater engagement of the public in proactively handling the world's most precious resource.
To date, more than 153,990 of the project's total 173,500 heliostats have been installed. Several stunning photos below show recent progress at the site.

The SolarEdge PV inverter combines sophisticated digital control technology with efficient power SolarEdge's EV charging single phase inverter offers homeowners the ability to charge electric vehicles up to six times faster than a standard Level 1 charger through an innovative solar boost mode that utilizes grid and PV charging simultaneously. This product is the world's first EV charger with an integrated PV inverter. Reducing the hassle of installing separately a standalone EV charger and a PV inverter, the EV charging inverter eliminates the need for additional wiring, conduit and a breaker installation. By installing an EV charger that is integrated with an inverter, no additional dedicated circuit breaker is needed, saving space and ruling out a potential upgrade to the main distribution panel. Whether you own an EV now or just want to be EV-ready, future-proof your home with SolarEdge.
