It was about an astronaut who crashed and his missing bits were replaced by bionics. When you take into account the cost to maintain the aircraft, the fuel, the pay for the instructors, a bunch of other costs, and my pay (last in the list on purpose), I was the Eight Million Dollar Man, in 1990 dollars. Today, the costs are much higher.
Renewable energy refers to the provision of energy via renewable resources which are naturally replenished fast enough as being used. It includes e.g. sunlight, wind, biomass, rain, tides, waves and geothermal heat. Renewable energy may replace or enhance fossil energy supply various distinct areas: electricity generation, hot water / space heating, motor fuels, and rural (off-grid) energy services.
In order to define alternative energy we first need to define alternative energy sources. Alternative energy source is any source of energy that does not belong to traditional energy sources. Traditional energy sources are fossil fuels (coal, oil and natural gas).
