How to Install a Solar Air Heater
Solar air heaters are extremely environmentally friendly and they will greatly reduce your home’s carbon footprint and energy bills. They require little or no maintenance and they will last for years. Diagram of a solar air heater Solar air heaters heat air in an “air collector.” The system absorbs and collects solar radiation and transfers the solar heat to a storage system or straight to the interior space. From there the heat is distributed. To install a solar air heater, you must first calculate the system you will need for heating your space. Calculations should be based on the average heat load for your cold season. If you base it on the coldest, your system will be over-sized most of the year. A wood burning or gas stove can be used for the coldest days in addition to your heater

Australians of the future will look back on [opposition leader Tony] Abbott’s campaign with pity and shame. The pity and shame posterity reserves for leaders who miss the wave of history and misjudge the big calls.
BINGAMAN: The starting point for the [Senate briefing by oil experts] was one fundamental truth: the primary driver of the price for gasoline at the pump is the price of crude oil. This chart [above] was one of the key ones used by EIA Administrator Newell. It shows the price trends since 2005 for gasoline (in yellow) and crude oil (in green)…. [F]or the last 3 years, gasoline price movements have exactly tracked global crude oil prices. The idea that our gasoline prices are high today because of some policy of the Obama Administration is just not supported by the facts…. The bulk of the discussion at the briefing that we held on Tuesday about high oil prices was about what is going on in the Middle East and North Africa. It should be obvious that this is the major force driving oil prices…. As you can see from this chart [below], oil prices are very sensitive to these kinds of developments…. But what can Congress do to help ease the burden of high prices for U.S. consumers, when oil prices are determined mostly outside our borders? I think a realistic, responsible answer has to be focused on becoming less vulnerable to oil price changes over the medium- and long-term. And we become less vulnerable by using less oil. Senator Bingaman (D-NM), who is not known for his eloquence, gave a better speech on oil last week than President Obama ever has. Why? Why are Democrats so lame in talking about this potentially winning issue

Guest blogger Jon Coifman is a communications strategist on environmental and clean technology issues, and author of the blog PositioningGreen.com . Billionaire conservative financier David Koch doesn’t know it, but the cutting-edge energy-saving technologies included in a brand new $211 million research lab that bears his name were partly funded through a government program to reduce global warming pollution. It happens to be the very same program under a blistering attack by one of Koch’s biggest political beneficiaries, the group Americans for Prosperity.
