Importance of energy efficiency has emerged from various supply scenarios and is further underlined by rise of prices in energy sector and subsequent areas
Rods of uranium are placed inside the nuclear reactor. The fission chain reaction is slowed down by lowering boron control rods into the reactor core and increased by raising them. The heat of the reaction is carried away from the core by a coolant (water, gas or pressurized water) and used to create steam outside the reactor.
Obtaining a secure and adequate supply of a traded commodity, be it food or fuel, is generally a problem prevalent amongst poor people, poor regions or poor nations. With the power to pay the price the rich often find willing suppliers for what they want. The World Energy Assessment (UNDP 1999) report defines energy security as: “the continuous availability of energy in varied forms in sufficient quantities at reasonable prices”. This definition needs to be modified to better reflect our situation in India.
The signing of Paris agreement by India, concomitant with its submission for Intended Nationally Determined Contribution (INDC), has charted out the path that India plans to adopt for energy security. While India’s plan in the past has always looked good on the paper, how far India would be able to meet the target leaves a big question mark. In addition, India’s submission to INDC fails to address how India would meet its energy security in the transportation sector.
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.
