Power Electronics for Renewable Energy System

Developing renewable energy technologies that exploit the sun the wind and geothermal energy is critical to addressing concerns about climate change and some environmental issues. However using renewable energy sources will not eliminate all environmental concerns. Although renewable energy sources produce relatively low levels of Green House gas emissions and conventional air pollution manufacturing and transporting them will produce some emissions and pollutants. The production of some photovoltaic (PV) cells for instance generates toxic substances that may contaminate water resources. Renewable energy installations can also disrupt land use and wildlife habitat and some technologies consume significant quantities of water.To develop sound policies Policy makers must understand the relative environmental impacts of alternative energy sources including how the impacts of renewable energy technologies compare to those of fossil-fuel technologies and to opportunities for improvements in energy efficiency. Understanding the potential environmental impacts of renewable energy technologies is also essential for identifying and pursuing design manufacturing
