Man has mastered so many arts, from intricately carving artefacts to building ballistic machines! Making power by burning fuels such as coal, petroleum or natural gas was one such achievement that lighted up our lives. Thermal generators or specially designed furnaces produce this wonderful thermal electricity. Thermal power plant burn fuels to boil water and make steam. The steam is then used to spin a turbine which is connected to a generator that weaves electricity. Turning on a light or a fan seems...
Population explosion has resulted in manifold increase in demand for energy. The conventional, non-renewable sources of energy, such as coal, petroleum, natural gas, etc. are experiencing extensive pressure, resulting in an urgent need to switch to non-conventional sources of energy which are renewable and ecologically safe. For instance, solar, geothermal, wind, biomass, tidal and wave energy fall under non-conventional sources. Maximum utilisation of renewable sources will facilitate generating...
LEDs consume less energy, have better light quality and are robust. Once the drawbacks - high cost and photobiological effect - are resolved, they may allow the phase out of mercury-containing CFLs.
Though CFLs consume a fifth of the energy required by incandescent lamps, they contain highly toxic mercury. The absence of fixed standards for mercury content and the lack of disposal norms, even a decade after CFLs were introduced in India, mean there are huge quantities of mercury lying in our waste, seeping into our atmosphere and entering our food chain.
Despite efforts to enhance domestic energy production and diversify fuel mix, India still faces energy and peak shortages of around 8 per cent and 12 per cent respectively, while a large section of the rural population continues to lack access to clean and efficient energy fuels to meet their daily requirements.
There is an intrinsic relationship between energy uses and economic development and India needs, at the very least, to increase its primary energy supply by 3 to 4 times and, its electricity generation capacity/supply by 5 to 6 times of their 2003 levels.
The humble green stuff that affably lines water bodies and is treated with disdain, is now positioning itself to save the earth. Biological fixation of carbon dioxide is an attractive option because plants naturally capture and use carbon dioxide as a part of the photosynthetic process.
