This is another one of those terms that has been improperly defined and widely used to imply that the energy created is fossil-fuel free and low or zero emissions. It is not true.<br /><br />All of the costs and carbon emitted by the development of wind turbines, tidal, solar or whatever "clean energy" source has to be factored in, including raw materials, design and maintenance over the entire life-cycle. It must also be remembered (and calculated) that at every step of the life-cycle, fossil-fuels are still being extracted and burned in support of these devices.<br /><br />A thousand-mile range in 10 years is not going to make much of a difference. The true costs of high-density batteries and their development, waste and pollution (and carbon emissions in their life-cycle) must also be calculated. Electric planes are not carbon-free - they are carbon intensive creations.<br />Anonymousnoreply@blogger.com
