So far, it has been a big year for the U.S. wind industry, which experienced its fastest first-quarter growth since 2009. In total, about 2,000 megawatts of new capacity was installed, enough to power about 500,000 homes. With this addition, wind now produces 5 1/2% of the country’s electricity.
Natural world heritage sites exemplify the world’s greatest areas of natural beauty, ecology, geology, and biodiversity. They are recognized internationally for their value as places with significance that is “so exceptional as to transcend national boundaries and be of common importance for present and future generations of all humanity.” Many of these areas also are a vital source of food, fuel, and water for rural communities, and provide a revenue stream for national economies through tourism and recreation. The livelihoods of some 11 million people are directly dependent on these areas.
Our nation’s landfills are overflowing and we are constantly seeking ways to reduce the amount of waste that needs to go into them. Usually, we are thinking about food waste, plastics, glass and paper. However, one of the largest sources of waste generation is actually construction and demolition waste. Estimates are that between 25 and 40% of the national solid waste stream comes from these activities and very little of it gets recycled.
