Please see the article by Sam Carana on how a larger grid, yet a simultaneously more locally-run grid, can be implemented. The purpose is to capture as much of the electricity being generated as possible while keeping a local level of control, to try to avoid undue influence by those who fail to understand the details of energy policy. Read about how many parts of Europe already have surplus electricity, and how countries are linking their grids together to improve efficiency. Part of the rationale for such arrangements in Europe is that countries which generate a lot of electricity from wind can necessarily control when that electricity is most plentiful, but they don’t want it wasted. At the same time, such European countries may need electricity from other sources, say hydroelectric plants in a neighboring country, when wind power isn’t sufficient. Similar arrangements could be made throughout North America. See what Sam has to say! He gives lots of sources for his comments and information.
Michelle Bennett of Cleantechnica.com with the latest on solar concentrators coupled to solar panels: “We already know that concentrated solar power (CSP) is shaking things up in the solar industry. A subset within the industry is turning up the heat. “Extreme” Concentrated solar magnifies intense sunlight onto a solar cell, at temperatures that could melt it, to boost efficiency for less money.” and “Sunrgi hopes to bring their product to market in about a year, so we’re not talking about pipe dreams. These guys are serious, and they’re out to make some money at 5 cents/kwh. But fortunately for us all, this technology is not new, and Sunrgi is not the first to point a magnifying glass at a solar panel. The Aussies beat us to it.”

The cost of solar and wind power installations keeps dropping, for the most part, with occasional, temporary price rises in the solar area if silicon supplies are an issue. The following links all point to a site that offers information on practical solutions and tax rebates in different regions.
Here are a few ways you can bring solar power to your own home with the help of expert installers:
1.1kW Grid-Tied Solar Electric System
Here are a few ways to bring wind power to your home:
Air Breeze Land Wind Turbine
Skystream 3.7 Grid Tie 1.8kW Wind Power System
Here is a battery to store the clean power you generate:
Xantrex XPower 1500 W/60 AH BATTERY
I hope that you find these resources useful.

An environmentally friendly technology using temperature differentials in the Tropical Ocean combined with other technologies could enable global Hydrogen distribution, by Mahesh Basantani for Inhabitat.
“Ocean waves are already being used as a source of renewable energy, but could differences in water temperatures in the sea be our next source of green power? A decade old idea to generate renewable electricity for the globe with offshore, floating ‘Energy Islands’ could soon become a reality. The concept – creating artificial islands to collect wind, wave and solar power in the tropics – is based on the work of Jacques-Arsène d’Arsonval, a 19th-century French physicist, who envisioned the idea of using the sea as a giant solar-energy collector.”
While considering this story, I also urge you to read Sam Carana’s articles on the distributed electrical grid, a hydrogen economy and electric cars. He offers compelling arguments to do away with liquid fuels, coal and nuclear power as soon as possible, and to invest in solar, wind, and geothermal power industries that are supplemented by the use of biomass to generate hydrogen (the cleanest of fuels, I would say).
