Energy Crises Energy is considered to be life line of any economy and most vital instrument of socioeconomic development of a country. Energy is pivotal in running machinery in factories and industrial units‚ for lighting our cities and powering our vehicles etc. There has been an enormous increase in the demand of energy as a result of industrial development and population growth‚ in comparison to enhancement in energy production. Supply of energy is‚ therefore‚ far less than the actual

Geothermal Energy Introduction The Geothermal is a clean and sustainable (renewable) energy. It has been estimated that the heat of the centre of the earth may reach 6000°C. It has been found that the increases one degree °C for 30-50 meters. The word geothermal is derived from Greek language where the first syllable “Geo” means “earth” and the second syllable “thermal” means “heat”. How it works The geothermal energy should be made useful through electrical generators. We are not free to dig

Renewable energy is energy that comes from resources which are continually replenished such as sunlight‚ wind‚ rain‚ tides‚ waves and geothermal heat. About 16% of global final energy consumption comes from renewable resources‚ with 10%[discuss] of all energy from traditional biomass‚ mainly used for heating‚ and 3.4% from hydroelectricity. New renewables (small hydro‚ modern biomass‚ wind‚ solar‚ geothermal‚ and biofuels) accounted for another 3% and are growing very rapidly.[2] The share of renewables

Energy Transformation Conduction‚ convection‚ and radiation are things that exist in our life. Thanks to that stuff we have things like electricity and things to cook too. I am going to explain things about energy transformation. Heat transfer is the way heat moves through matter to change the temperature of other objects. There are three types of heat transfers‚ Conduction‚ Convection‚ and Radiation. The first kind of heat transfer‚ conduction‚ is heat transferring through direct contact of materials

Solar Energy The Sun is a star and without it there would be no life on earth. This is why the Sun is called the ultimate source of energy. The Sun’s energy is produced by a process called nuclear fusion. Every second‚ the Sun emits vast amounts of energy‚ much of which is light‚ and this solar radiation can be converted into electricity. Plants and trees are pretty good at collecting this energy. With the help of green chlorophyll‚ they use light energy to make food – they’re our solar powered

Thailand’s Experience whit clean energy technology Past achievements were considerable; still there is a wide window of opportunities to further promote clean and renewable energy technologies so that the country can better realize its full potential. Renewable energy currently makes up only a small percentage of the total electricity mixes in the country. Advanced clean fossil-fuel based technology is left largely unexplored despite the continued significance of fossil fuels in Thailand. It
