We believe that our home, our "pale blue dot" in the immortal words of Carl Sagan - planet Earth - is an amazing and wonderful natural creation that it must be our top priority to look after for future generations. Humanity has in recent decades become aware that its extraction and burning of fossil fuels (coal, oil and natural gas) to provide energy is, through the release of carbon dioxide into the atmosphere, causing a "greenhouse effect" contributing to the heating of the planet. The concern is that the rise in temperature may generate feed-back loops that eventually reach a tipping point, leading to runaway warming and a "hothouse Earth". Belatedly - though not yet too late - it has begun to make the switch away from such dirty sources of energy to new clean ones. At Clean Energy Revolution, we campaign for an effective energy transition from fossil fuels to a mix of renewables and nuclear power. Wind, solar, geothermal, hydro, tidal, wave, biomass and nuclear are among the leading alternative sources of energy capable of replacing fossil fuels in powering our societies. Which to select? We argue that the precise energy mix for a country will, to a large extent, be a matte
