Electric Power from Renewable Energy: Realities for Policy-Makers

摘要: Current wind and photovoltaic technologies are incapable of providing the all-renewable electric power future that many have envisioned, because inherent mismatch between their unpredictable, intermittent nature society's demands for on demand. Paths using these in combination with storage or as fuel-savers fossil-fueled plants. In a cloudless world, costs double if is needed at night, when there clouds, escalate dramatically. Electric from turbines varies cube velocity, which can fluctuate zero to high values over short periods. To make competent national energy policy, public policymakers need an unbiased, authoritative analysis maximum possible, long-term contributions renewables U.S. needs.
