TweetThe US consumes about 23% of World electricity. China consumes about 17% with Russia and Japan consuming about 5.7% each. All the countries of the EU combined consume about 17% of World electricity. A more meaningful figure is consumption per … Continue reading
TweetThe splitting of atoms (fission) releases vast amounts of thermal energy which can be used to boil liquid to expand as steam, turn a turbine which in turn rotates a generator to generate electricity. Nuclear energy meets 16% of electricity … Continue reading
TweetConservation of energy and resources. To reduce planet energy consumption, it is essential to reduce the energy requirement of its occupants. Buildings must be redesigned to lower energy requirements. Transport systems must be redeveloped to improve efficiencies.
TweetStorage of energy. Energy generated by alternative sources is difficult to store. Batteries, stored water, air and heat can all be used to store energy for future use. Fuel cells struggle to overcome high costs. While the size and complexity … Continue reading
TweetElectric propulsion (i.e. electric motor) technology, is set to become the engine to replace all engines. Electric motor technologies consequently constitute a unique, quickly evolving and separate division of the whole alternative energy sector.
TweetAlternative engines both improve upon current ICE designs while continuing to use fossil fuels, biofuels or both. Several designs are in development which seek to improve on thermal energy. In parallel, the engine combustion process is being rethought with catalysts … Continue reading
TweetAlternative fuels replace some fossil fuels in our transport system. Bio-fuels are ethanol, biodiesel, biogas and others. They use fossil energy in their production, contribute to carbon footprint and require vast land areas and water to grow raw materials. Their … Continue reading
TweetAlternative energy generation technologies comprise the use of wind, water, biogas, the sea and possibly geothermal heat to generate electrical energy. All these technologies no matter how micro, definitively replace the use of fossil fuels (coal and oil) to generate … Continue reading
TweetAt least 35% of all Planet tapped primary energy is converted into electricity. Among Developed Nations an average of 42% of all primary energy is converted into electricity. Coal is used to generate about 40% of Planet electricity and its … Continue reading
TweetApproximately 18,000 terawatt-hours (TWh) per annum. It is anticipated that electricity demand will double in the next 20 years to a yearly demand of over 32,000 TWh. The really important question therefore is how will we generate this increased electricity?
