Biofuels have been around as long as cars have.

A biofuel is a fuel that contains energy from geologically recent carbon fixation. These fuels are produced from living organisms.

Generating Electricity from Wing Waves.

Wind turbines, like windmills, are mounted on a tower to capture the most energy. At 100 feet (30 meters) or more aboveground, they can take advantage of the faster and less turbulent wind.

Producing electricity from solar energy.

Solar energy is a free, inexhaustible resource, yet harnessing it is a relatively new idea. The ability to use solar power for heat was the first discovery.

Turbines catch the wind's energy with their propeller-like blades.

A blade acts much like an airplane wing. When the wind blows, a pocket of low-pressure air forms on the downwind side of the blade.

Solar energy may have had great potential

Solar technology advanced to roughly its present design in 1908 when William J. Bailey of the Carnegie Steel Company invented a collector with an insulated box and copper coils.

We have been harnessing the wind's energy for hundreds of years.

For utility-scale sources of wind energy, a large number of wind turbines are usually built close together to form awind plant.

Biofuels are produced from living organisms.

In order to be considered a biofuel the fuel must contain over 80 percent renewable materials.

Geothermal energy is the heat from the Earth.

Resources of geothermal energy range from the shallow ground to hot water and hot rock found a few miles beneath the Earth's surface, and down even deeper to the extremely high temperatures of molten rock called magma.

Geothermal heat pumps can tap into this resource to heat and cool buildings.

A geothermal heat pump system consists of a heat pump, an air delivery system (ductwork), and a heat exchanger-a system of pipes buried in the shallow ground near the building.

In the future, civilization will be forced to research and develop alternative energy sources.

Possession of surplus energy is, of course, a requisite for any kind of civilization, for if man possesses merely the energy of his own muscles, he must expend all his strength - mental and physical - to obtain the bare necessities of life.

Current Affairs Indian Economic Survey 2014 15 From Carbon Subsidy To Carbon Tax Indias Green Actions

Current Affairs Indian Economic Survey 2014 15 From Carbon Subsidy To Carbon Tax Indias Green Actions
FROM CARBON SUBSIDY TO CARBON TAX: INDIA'S GREEN ACTIONS Economic Survey 2014-15 acknowledges the green actions taken by India, including imposing significantly higher taxation of petroleum products and thereby reenergizing the renewable energy sector. India shifted from a carbon subsidization regime to one of significant carbon taxation regime, from a negative price to an implicit positive price on carbon emissions.

India has cut subsidies and increased taxes on fossil fuels (petrol and diesel) turning a carbon subsidy regime into one of carbon taxation, by putting an effective price on emissions. This has significantly increased petrol and diesel price while serving as price signal to reduce fuel burnt and hence CO2 emissions.

Calculating CO2 emission reductions from measures taken for petrol and diesel suggests that there will be a net reduction of 11 million tons of CO2 emissions in less than a year compared to the baseline or 0.6 percent India's annual emissions.

In addition, India has increased the coal cess from Rs. 50 per ton to Rs. 100 per ton, which is equivalent to a carbon tax of about US 1 per ton. A higher tax on coal offsets the domestic externalities including health cost of coal for power generation. The Economic Survey points out that any rationalization of coal pricing must take account of the implications for power prices and hence access to energy for the poorest in India which is and must remain a fundamental objective of policy.

The Economic Survey observes that there is still a long way to go with potential large gains still to be reaped from reform of coal pricing and further reform of petroleum pricing policies.

Broadly, the move to substantial carbon taxation combined with India's ambitious solar power program suggests that India can make substantial contributions to the forthcoming Paris negotiations on climate change.
