People like to compare the cost to generate electricity from various renewable resources, like wind or solar, to the cost to generate electricity from coal, nuclear and natural gas. Comparing these costs is like comparing apples to oranges. Power generation is a complex business and without considering load factor; capacity (kW) and energy (kWh); and fixed and variable costs, these comparisons are not legitimate for evaluating power generation technologies.
Let’s begin with load factor, or the percentage of hours that a power plant operates at its maximum capability in a given time period. So if a 1,000 MW nuclear plant has an annual load factor of 98 percent, it is operating at 1,000 MW for 98 percent of the hours in a year.
Power plants can be categorized by load factor. Base load power plants typically have annual load factors that exceed 75 percent

A completely new concept of underwater wave energy using a simple 7 ton kite turbine design has been developed by Minesto; which is a spinoff from the Swedish military and aircraft design firm Saab. The Deep Green underwater turbine captures the power of the ocean just like a kite in wind.
The system could generate 18 terawatthours of energy annually, enough to provide nearly 4 million British households with reliably green electricity every year. UK households now use about a third of what average US households use in energy.Read the rest of this entry »
