Radioactive Waste Management | An Overview with Indian Perspectives

Understanding Radioactive Waste Nuclear, or radioactive waste is the waste product of nuclear reactors, fuel processing plants, research facilities and hospitals, and is also produced when nuclear reactors and facilities are dismantled. Radioactive waste is differentiated into high-level and low-level radioactive waste. While high-level waste is the spent fuel detached from nuclear reactors, low-level waste is generated from other scientific, industrial and commercial uses of radioactive materials...

Initiating Energy Efficiency in India: Need of the hour

Importance of energy efficiency has emerged from various supply scenarios and is further underlined by rise of prices in energy sector and subsequent areas

Nuclear Reactor Fuel Uranium- From Mining Ore to Energy

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.

Energy Consumption and Energy Security | A Rising Concern

Per capita energy consumption in India is amongst the lowest globally. With the power to pay the price the rich nations often find willing suppliers. 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 the situation in India.

Mission India: Energy Security now and for the future

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.


How thermal power is generated!

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...

Non-conventional Energy Sources in India

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 energy sources 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 energy...

Lead with LED

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.

The CFL conundrum

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.

Electricity Regulation in India

The Indian electricity sector, despite strings of reforms during the last one and half decades, is still struggling to close the gap between demand and supply. Power sector targets set for the last three five year plans were not achieved. Providing electricity to much of the consumers, households and industries, at competitive rates with a good quality of service thus still remains a challenge.
