People have known for decades that energy resources such as wind and solar are cleaner and healthier than energy produced by dirty fuels. But, utilities and consumers occasionally express concern about the variability and dependability of those renewable sources. Those concerns are fading with the emergence of game-changing energy storage technologies. According to a new white paper released today by Environment New York, the rapid growth of less expensive wind and solar energy and the plummeting costs of energy storage have led to a six-fold increase in energy storage capacity (excluding pumped hydropower) over the past decade.

A unique partnership between Penn State and industry members is working to advance solar and wind energy through energy storage and microgrid systems education and training.

Alternative power sources are rapidly becoming a crucial part of the global power sector due to the rising acknowledgment of the environmental damage caused by fossil fuels. Despite rising public and government support, the key obstacle in the path of the alternative energy market has consistently been the fluctuations in the energy output achieved by the use of most alternative energy sources. The lack of a reliable energy storage technology that will allow for long-term storage of the energy generated from renewable energy sources has exacerbated the problems holding back the alternative energy sector and is thus likely to be a key area of research in the coming years. 

General Motors has made its largest renewable energy procurement to date, purchasing enough wind power to equal the electricity needs of 16 of its U.S. facilities.
