Energy efficiency, cleaner grid would cut carbon pollution from buildings
From lighting to heating and cooling buildings consume almost a third of the energy used in the US that means they produce a lot of carbon pollution. Gop Harris is with the National Renewable Energy Laboratory in a recent study, he and his colleagues found that within thirty years the US building sector could cut its energy related carbon dioxide emissions by almost eighty percent over two thousand and five levels. But getting there requires major changes. One Big One is really driving energy efficiency in buildings residential and commercial. For example, high performance windows insulation can greatly reduce the need for heating and cooling. Harris says, it's also important. Have Buildings Run as much as possible on clean electricity that means shifting the grid to renewables and using that clean electricity to run systems that were previously powered by natural gas such as heating and cooling. We have to have this sort of combined strategy moving towards trinity and moving that electricity towards zero carbon sources when those happened together then we get to the point where we can actually achieve our targets and avoid dangerous levels of global warming.
