From Guest Blogger Mary Alice Khatcherian: What Does It Mean To Use Green Energy Sources?

Swap your old appliances for newer ones that have an Energy Star rating. Energy Star appliances are guaranteed to use less energy than those made previously. For refrigerators and freezers, the rating promises 20% less energy used, for dishwashers 40% less energy used, and for washing machines at least 50% less energy used!
Those looking to reduce their energy consumption would be wise to make their own ice. Though automatic ice makers may seem convenient, they often break a lot and waste a lot of energy. Additionally, seals that leak are another common complaint with these devices, and this can lead to a general rise in temperature within the freezer. If you make your own ice, you won’t have these problems. Read More

Adjust the settings on the thermostat to reflect the various seasonal temperatures. Keep the house at a slightly lower temperature in winter and raise the temperature slightly in the summer. In addition to doing this, try wearing less or more clothing (depending on the weather), and reduce energy usage in your home and keep your temperature reasonable.
Decorate with brighter wall colors to save electricity. If your walls feature darker colors, you’ll need more electricity to make your space as bright as you want it. With lighter colors in place, you will find the need for illumination is decreased. The house will have a lighter feel and look, as you save money. Read More

When you are preparing to install a solar energy system, ensure that the power storing batteries are located nearby to the cells. This prevents power from getting lost in the cables. It also reduces shading of the solar shells. Shading reduces solar panel energy generation.
Replace any leaky windows with weather-sealed efficient ones. There are several benefits in using these windows, including a decrease in energy bills and less condensation on the windows. Read More
Basics of Renewable Energy
| April 20, 2012 | Posted by Craig Shields under Renewables - Science |
Just a quick note to let you know that our project to assemble audio/visual learning aids aimed at renewable energy is complete (for now, at least), and ready for distribution to any young people or newcomers in the subject you feel may benefit. It’s a compilation of a few short videos, in which I lay out each of the five major “flavors” of clean energy (solar, wind, biomass, geothermal, and hydro), and briefly discuss the strengths and weaknesses of each. Also included are “infographics” that further explore these technologies and the issues that surround them.
My aim, of course, is to introduce this subject to as many people as possible, in the hopes that we can drive up the number of informed discussions, so necessary to the success of the democratic process.
Please feel free to send this link to anyone in your life who you feel may benefit. Thanks.

Is Renewable Energy Growing Stronger? It Depends on How You Look At It
| April 9, 2012 | Posted by Craig Shields under Renewables - Business |
EVWorld has a wonderfully encouraging article on renewables that begins:
Pop quiz time. The fastest growing energy sector in terms of percentage of growth in the United States between January 1, 2009 and December 31, 2011 was: A) natural gas, B) nuclear power, C) renewable energy?
The answer is C, renewable energy (RE) by a huge margin. According to the U.S. Energy Information Agency (EIA), RE grew by 27.12%. That includes biofuels, biomass, geothermal, solar, water, and wind. By comparison, natural gas production increased 13.66%, while crude oil grew 14.27%. Nuclear power, in contrast, shrunk 1.99% and coal dropped 7.16%.
All true, but one can find different facts that would support a different conclusion. E.g., under 5% of the U.S. grid mix is renewable energy (if you don’t count hydroelectric dams), so talking about percent growth of this small number may not be the most relevant stat.
From Guest-Blogger Joshua Okomo: Global Investment in Renewables Exceeds Non-renewables
| January 24, 2012 | Posted by okomo under Renewables - Business |
Assessment of energy investment in the world shows a clear path to bigger investment in renewable than non renewable. Clean energy technology is making clear progress globally, in some countries current and planned deployment of renewable far outstrip investment in non renewable energy.
More aggressive clean energy policies are required, including the removal of fossil fuel subsidies and implementation of transparent, predictable and adaptive incentives for cleaner, more efficient energy options. Due to government support and investors strategy for capital returns, solar PV and wind power are achieving strong growth. However for many developing countries where the natural potential for solar and wind power is even higher, much effort is needed in solar and wind power deployments.
From Guest Blogger Jim Stack: Hawaii — Land of Oil or Renewables
| December 1, 2011 | Posted by jstack6 under Renewables - Science |
Hawaii has been known as a land of paradise. They have a great climate and can grow anything anyplace. But did you know Hawaii runs most of paradise on oil-generated electricity? Of course, all of the oil is imported too.
Recently becuase of fast growing prices they started looking at renewable energy in Hawaii. They found they have great solar, wind, hydro wave and currents and even geothermal energy. They are now just starting to develop these great renewable energy sources.
In Hawaii they have have many small islands and micro grids that are not connected. This makes it difficult to combine all the great renewable energy sources they have into an efficient grid. Read More
By Guest-Blogger Don: Wanted, People Who Can Grow a Company by 8% (per month)
| October 25, 2011 | Posted by Donald W under Photo-voltaics |
I was giving a speech earlier this month about Energy Security, and while preparing the speech came upon some stark realizations about electrical generation in the US:
1) Solar is equivalent to an insignificant rounding error for electrical generation in the US.
2) Coal will remain by far the dominant form of electrical generation assuming the status quo for at least 5 years and will probably be the first or second generator for 10 years.
3) Assuming current trends, solar not be out producing petroleum product (petroleum liquids, petroleum coke) for about 4½ to 5 years.
4) Growth of 40% per year in 5 years solar will still be a rounding error for electrical generation in the US.
5) With growth of 60% per year in 5 years solar will finally achieve the status of being a rounding error for electrical generation in the US. Read More
Talking Renewable Energy on “Getting Your Money’s Worth”
| October 12, 2011 | Posted by Craig Shields under Renewables - Science |
Many years ago I donated 90% or so of my neckties to charity as I almost never wear one anymore. But I’m glad I didn’t get rid of them all, as here I had a rare opportunity a couple of weeks ago when I was in New York City and taped an episode of “Getting Your Money’s Worth,” in which I discuss renewable energy with show host Judith West. (The video displays better on Internet Explorer than other browsers.)
It was actually quite a rocket ride, where Judith asked about solar, wind, fossil fuels, electric transportation, and a range of other subjects concerning the politics of clean energy.
