WASHINGTON — As Congress weighs imposing a mandatory limit on climate-altering gases — an outcome still far from certain — it is likely to turn to a system that sets a government ceiling on total emissions and allows polluting industries to buy and sell permits to meet it.
That approach, known as cap and trade, has been embraced by President Obama, Democratic leaders in Congress, mainstream environmental groups and a growing number of business interests, including energy-consuming industries like autos, steel and aluminum.

Environmentally-friendly Cooling With Magnetic Refrigerators

ScienceDaily (May 17, 2009) — Scientists are a step closer to making environmentally-friendly ‘magnetic’ refrigerators and air conditioning systems a reality, thanks to new research published May 15 in Advanced Materials.
Magnetic refrigeration technology could provide a ‘green’ alternative to traditional energy-guzzling gas-compression fridges and air conditioners. They would require 20-30% less energy to run than the best systems currently available, and would not rely on ozone-depleting chemicals or greenhouse gases. Refrigeration and air conditioning units make a major contribution to the planet’s energy consumption – in the USA in the summer months they account for approximately 50% of the country’s energy use.
