The Nuclear Debate Sam Beattie Fossil fuels take millions of years to form‚ which means they are non-renewable resources. We are using those 100 000 times faster than they are being made. When we use fossil fuels to get energy we get more than just energy. Greenhouse gases and air pollution are made too. The 3 main fuels are coal‚ oil and natural gas Nuclear power uses fission to produce energy. Nuclear fusion also has potential for energy production. Around 6% of the world’s energy and 14%

The energy that is used today comes from fossil fuels‚ which is a nonrenewable limited resource that will eventually be used up. Alternative energy sources such as solar‚ hydroelectric‚ geothermal and wind energies can be used‚ to conserve the planets limited natural resources. Alternative energy is the use of another energy without the burning of fossil fuels and break up on atoms. Solar energy can be used to operate cars and provide electricity for homes and businesses.

We do not know what energy exactly is‚ we use this term to describe a capacity of a physical or biological system for movement or change. Energy comes in many forms

Industrial Revolution. These changes occur due to increased burning of fossil fuels and other human activities. The discharge of green house gases like carbon dioxide‚ methane‚ nitrous oxide etc. into nature (Also see Nature Essay) is another reason for rising temperature of earth. * Buildings‚ both commercial and residential represent a larger source of global warming pollution than cars and trucks because they require a lot of fuel to be burnt which emits a large amount of carbon dioxide. * Effects

We have indeed become acquainted to this lifestyle of capitalistic gain in an attempt to achieve economic success through the production of cheap plastics that have revolutionized commerce and the extraction and burning of inexpensive fossil fuels that energize the work and entertainment of our everyday lives.

Since the beginning of time‚ the built environment has been an integral part in providing shelter needs for men‚ women and children. Maslow (1943) formulated that shelter is a basic requirement of humans. In the future‚ humans will have to construct sustainable shelter otherwise would they would risk depleting resources for subsequent generations. Construction is an example of a multitasking activity. The lifecycle of construction can be broken into phases. Achieving building sustainability in

are causing climate change by burning fossil fuels and cutting down trees. Too bad trees don’t provide us with Wi-Fi or money‚ we’d be planting them like crazy‚ unfortunately‚ however‚ they only provide us with the oxygen that we breathe. There shouldn’t be any debate about whether global warming is real or not‚ we know its real‚ there’s numerous evidence to support that‚ instead it should be what we’re going to do about it. Coal‚ the world’s dirtiest fossil fuel‚ accounts for about 30% of carbon emissions

Man-made disasters are the consequence of technological or human hazards. Examples include stampedes‚ fires‚ transport accidents‚ industrial accidents‚ oil spills and nuclear explosions/radiation. War and deliberate attacks may also be put in this category. As with natural hazards‚ man-made hazards are events that have not happened‚ for instance terrorism. Man-made disasters are examples of specific cases where man-made hazards have become reality in an event. Global warming Global warming is

With population explosions and the demands of modern lifestyles‚ the world’s need for energy production has become far too much for fossil fuels to keep up with. Experts say that the Earth’s stores of petroleum will be depleted by 2050.

Oil Conservation Fortnight (OCF) - 4th – 19th January Petroleum or crude oil is a non renewable energy source that means it is present in the limited amount. If the use of oil will continue with the careless nature it is going to exhaust definitely at one day. Hence conservation of this valuable resource is the need of the hour. Therefore in order to generate awareness among the masses about the urgency of conserving petroleum products‚ the celebration of an Oil Conservation
