Renewable energy could fully power a large electric grid 99.9 percent of the time by 2030 at costs comparable to today’s electricity expenses, according to new research ("Cost-minimized combinations of wind power, solar power and electrochemical storage, powering the grid up to 99.9% of the time") by the University of Delaware and Delaware Technical Community College. A well-designed combination of wind power, solar power and storage in batteries and fuel cells would nearly always exceed electricity demands while keeping costs low, the scientists found. “These results break the conventional wisdom that renewable energy is too unreliable and expensive,” said co-author Willett Kempton, professor in the School of Marine Science and Policy in UD’s College of Earth, Ocean, and Environment. “The key is to get the right combination of electricity sources and storage — which we did by an exhaustive search — and to calculate costs correctly.” The authors developed a computer model to consider 28 billion combinations of renewable energy sources and storage mechanisms, each tested over four years of historical hourly weather data and electricity demands. The model incorporated data from within a large regional grid called PJM Interconnection, which includes 13 states from New Jersey to Illinois and represents one-fifth of the United States’ total electric grid.
Total energy savings are estimated at about 16,200 megawatts per hour every year, the equivalent of planting more than 65,500 trees.
America spends approximately $1.6 billion on public housing energy payments every year. To put that into perspective, that's equal to: 15.7 percent of the annual budget of the U.S. Environmental Protection Agency 95.7 percent of U.S. investment in energy-efficiency and renewable energy programs.
Deerfield Beach (August 16, 2012) – Three years of hard work, dedication to quality and superior performance have landed MSi the coveted award of one of the top 500 fastest growing companies in America. Everything about MSi is HOT – except their light bulbs.
The National Park Service made the decision to install MSi iPAR 38 LED lights to illuminate the Liberty Bell located in Philadelphia, Pennsylvania. In 2003 the bell was moved into the new Liberty Bell Center, a glass and steel pavilion that allows it to be viewed by the public 24 hours a da

You haven't installed a tile mount that is easier to install than the Solar Tile Mount manufactured by TRA Snow and Sun. Solar Tile Mount is used on all tile roof profiles: flat, mid, and high. It is made in the USA of aluminum alloy for strength and excellent corrosion resistance. Solar Tile Mount is built to allow more ease in installation with more rise from the tile surface to the rail for better air flow below panels. The adjustable base is longer than most allowing attachment 6" to the left or right to have the bracket in the base of the pan of the tile and still fasten to the rafter. Solar Tile Mount is adjustable for counter batten systems from ¾" to 3". The horizontal rail is directly above base fasteners giving greater uplift resistance than any other system. For superior waterproofing apply TRA Snow and Sun's butyl backed VersaFlash aluminum flashing. No tile flashing is needed on top of the tile for greater labor and material cost savings.
