One purpose of wind turbines is to provide pollution-free electric power at a reasonable price in an environmentally sound way. In this focus issue the latest research on the environmental impact of wind farms is presented. Offshore wind farms affect the marine fauna in both positive and negative ways. For example, some farms are safe havens for porpoises while other farms show fewer harbor porpoises even after ten years. Atmospheric computer experiments are carried out to investigate the possible impact and resource of future massive installations of wind turbines.
Variations in nearshore wave power at four shallowwater locations along the east and west coast of India are examined based on the measured wave data for one-year period. The study shows that along the west coast of India, 83–85% of the annual wave power is during the summer monsoon period (June–September), whereas at Visakhapatnam (on the east coast), 55% of the annual wave power is during the summer monsoon period. Along Puducherry coast in the east, wave power is relatively less with maximum value of 31.8 kW m–1.
The terms "green jobs" and "green economy" are in vogue due to the observation that many renewable energy technologies seem to create more jobs per unit of installed capacity and per unit power generated compared to fossil fuel technologies. From a policy perspective, it is not only important to estimate the overall employment effect but to probe further into the nature and distribution of jobs created. This article attempts to characterise jobs created for select RETs as a function of multiple attributes.

If you know that a sector has arrived when it makes for trade wars between countries, then solar energy clearly has.
