Renewables: A big win for district energy

摘要

Renewable energy has been around for centuries. Power from wind and water movement and solar thermal were used by ancient civilizations. Today, solar energy, wind and biomass all offer promises of reducing dependency on traditional nonrenewable energy sources such as coal, oil and natural gas. The need for renewable energy has never been greater, as the world simultaneously wrestles with climate change, increased demand for fossil fuels in developing countries and the concept of "peak oil," defined by Wikipedia as "the point in time when the maximum rate of global petroleum extraction is reached, after which the rate of production enters terminal decline."
