POWER TRANSFORMERS

摘要

Renewable power is the future. Although here to stay, it comes with challenges that must be met before wind power becomes more mainstream than it is today. Besides the uncertain future of the Production Tax Credit, stalled in Congress at this writing, there are questions regarding variable and uncontrollable factors. For example, what happens when the wind simply does not blow? There are also questions about state and federal government regulations, about competing energy sources and about emerging, advanced energy-storage technologies. Finally, there are questions regarding energy efficiency, such as wind farms sited in locations so remote it is hard to get good returns on investment.
