View this complete post...The election is over and the people have spoken. After months of highly-charged attacks, lively and lackluster debate performances, and never-ending punches and counterpunches, Barack Obama has prevailed as the winner of the 2012 election. It won’t be an easy job. Mr. Obama will need to enable the creation of millions of new jobs, embolden U.S energy, environmental, and national security, and lead our country into a robust economic future – all while dealing with a sharply divided electorate.

It takes water to produce electricity. As many Americans retreat to air-conditioned environments to get out of the heat, the flame increases under our limited freshwater resources. The electrical energy used to create our comfort zones requires massive withdrawals of water from our rivers, lakes and aquifers to cool down nuclear, coal and natural gas power plants.
Transportation Issues Daily First-half 2012 sales of electric and plug-in hybrid vehicles hold some good and bad news for transportation and environment stakeholders.

This white paper focuses on the potential benefits to health, safety, and equitable distribution of resources for urban communities that green infrastructure can provide. Green infrastructure practices, such as rain gardens, green roofs, and permeable pavement, are designed to capture rainwater where it falls where it can infiltrate onsite to minimize pollution impacts to nearby streams and rivers.
BLUEGREEN ALLIANCE
Building energy use is responsible for about 40 percent of U.S. greenhouse emissions. Residential buildings account for nearly half of those emissions, and more than 85 percent of residential emissions are attributable to the 79 million single-family homes nationwide. California is home to more than 10 percent of such properties—approximately 8.4 million. If we are truly going to achieve meaningful energy efficiency (EE) and carbon savings nationwide, we must transform the residential marketplace.
