were replaced by fossil fuels such as coal and petroleum. At various times throughout the nineteenth and twentieth centuries‚ people believed that fossil fuel reserves would be exhausted and focused their attentions on sources of renewable energy. This led to experiments with solar steam for industry and solid wood‚ methanol gas‚ or liquid biofuels for engines. Attention has refocused on renewable energy sources since the 1960s and 1970s‚ not only because of concern over fossil fuel depletion‚ but

It happens when greenhouse gases such as carbon dioxide‚ water vapor‚ nitrous oxide‚ and methane trap heat and light from the sun in the earth’s atmosphere‚ which increases the temperature. Greenhouse gases are released mostly by the burning of fossil fuels for transportation‚ heating‚ electrical appliances and manufacturing‚ but they are also released as a result of the natural decomposition of organic materials‚ wildfires‚ deforestation‚ and land-clearing activities. The diffusion of these gases

energy revolution that launched the industrial age. The catalyst to this epochal change was ordinary black coal - an energy rich hydrocarbon. A century later‚ oil and gas were added to satiate the thirst of industry. Man still relies mainly on these fossil fuels. Nevertheless many other sources of energy: hydro‚ solar‚ nuclear‚ wind‚ geothermal‚ biogas and wave have been taped. These sources of energy are not only renewable but clean as well. Since the hydrocarbons are exhaustible and their use

Fossil fuels are not an infinite source but a finite source. Scientists do not know the exact process behind the creation of fossil fuels‚ except that the creation takes a very long time. Because fossil fuels are not unlimited and speculation has some fossil fuels disappearing by the end of the 21st century‚ many individuals believe

converted by other kinds of energies‚ especially fossil fuels. According to the U.S. Energy Information Administration (EIA)‚ the most of the common fuel that used for electricity generation is coal sharing 45% of the U.S electricity energy‚ which is about 4 trillion Kilowatt-hours. Fossil fuels such as coal and petroleum are not renewable. Once they are used‚ the total resources of them are reduced. There will be one day that the earth is running out of fossil fuel.

The business as usual scenario involve the world to keep using the fossil fuels and the International Energy Agency predicts that fossil fuels will still dominate energy into 2030‚ which cancels out the predictions of fossil fuels running out by then with the growing population and the rapid development of nations such as China and India. This solution would involve natural gas consumption doubling

Hansen begins his essay by highlighting the problem that we are facing with global fossil emission and how the governments are failing to address this issue. He support his claim by proving examples where governments supports construction of new coal plant‚ liquid plants‚ development of unconventional fossil fuels‚ leasing of lands for oil and gas exploration

Fossil fuels and other nonrenewable resources have damaged earth because of the amount of pollution that is released some‚ in which is known as Carbon Dioxide. Massive amounts of Carbon Dioxide are that is released into our environment every year further damaging our planet. Scientist has been effectively working on ways of conserving energy

derived from fossil fuels. For years‚ we have been drawing on fossil fuels such as coal‚ oil and natural gas‚ as energy resources. However‚ with time these resources have gradually depleted leading to increase in the cost of energy. This had led experts to invent new sources of energy. The invention on renewable energy has not only provided an alternative energy resource but has also come with great environmental and socio-economic impacts.
