The primary rationale is to reduce air pollution and carbon dioxide CO2 emissions.
Its energy is found in fossil fuels as well as all living things. There is a great deal of information and enthusiasm today about the development and increased production of our global energy needs from alternative energy sources.
Solar energy, wind power and moving water are all traditional sources of alternative energy that are making progress. The enthusiasm everyone shares for these developments has in many ways created a sense of complacency that our future energy demands will easily be met.
Alternative energy is an interesting concept when you think about it. In our global society, it simply means energy that is produced from sources other than our primary energy supply: Coal, oil and natural gas are the three kinds of fossil fuels that we have mostly depended on for our energy needs, from home heating and electricity to fuel for our automobiles and mass transportation.
The problem is fossil fuels are non-renewable. They are limited in supply and will one day be depleted. There is no escaping this conclusion.
In fact, the earliest known fossil fuel deposits are from the Cambrian Period about million years ago, way before the dinosaurs emerged onto the scene. This is when most of the major groups of animals first appeared on Earth. The later fossil fuels — which provide more substandard fuels like peat or lignite coal soft coal — began forming as late as five million years ago in the Pliocene Period.
At our rate of consumption, these fuels cannot occur fast enough to meet our current or future energy demands. Dams are a major source of hydroelectric energy, such as the Hoover Dam on the Colorado River pictured.
While they collect the vast raw energy provided by water currents, they also create environmental hazards such as silt buildup. They are also significant barriers to fish, such as the salmon of the Pacific Northwest, which must migrate in order for the species to survive.
The Hoover Dam is a major source of energy for the southwestern US. Yet, governments such as the United States see its vast potential and are placing pressure on the further exploitation of nuclear energy.
US Department of Energy. A BTU is roughly equal to the energy and heat generated by a match. The problems occur when we destroy ecosystems while mining it and while using it.
Certainly, if there were a way that fossil fuels can be mined and used in ways that do not harm our ecology, then everything will be okay… in a perfect world. It is natural, with all things interdependent on each other to live, grow and produce.
Fossil fuel mining and oil production can and has caused irreparable damage to our environment. The Fossil Fuel Dilemma Fossil fuels exist, and they provide a valuable service.
Burning fossil fuels creates carbon dioxide, the number one greenhouse gas contributing to global warming. Combustion of these fossil fuels is considered to be the largest contributing factor to the release of greenhouse gases into the atmosphere.
The impact of global warming on the environment is extensive and affects many areas. In the Arctic and Antarctica, warmer temperatures are causing the ice to melt which will increase sea level and change the composition of the surrounding sea water.
Rising sea levels alone can impede processes ranging from settlement, agriculture and fishing both commercially and recreationally. Air pollution is also a direct result of the use of fossil fuels, resulting in smog and the degradation of human health and plant growth.
Oil spills have devastated ecosystems and coal mining has stripped lands of their vitality. Oil fossil fuels come from marine plants and animals and are found only underneath the ocean or under land that was covered by the oceans millions of years ago.
This oil rig is located offshore in the Arabian Gulf. Saudi Arabian Embassy — London The oil, coal and natural gas companies know these are serious problems. But until our renewable energy sources become more viable as major energy providers, the only alternative for our global population is for these companies to continue tapping into the fossil fuel reserves to meet our energy needs.
And you can pretty much count on these companies being there providing energy from renewable sources when the fossil fuels are depleted. Many oil companies, for example, are involved in the development of more reliable renewable energy technologies. Future Supplies for Future Energy Just how limited are our fossil fuel reserves?
Some estimates say our fossil fuel reserves will be depleted within 50 years, while others say it will be years. The fact is that neither one of these projections is very appealing for a global community that is so heavily dependent on fossil fuels to meet basic human needs.
We are going to run out of fossil fuels for energy and we have no choice but to prepare for the new age of energy production since, most certainly, human demands for energy will not decrease. Modern windmills have become very efficient at transferring the energy of wind to electricity. Wind power is an important part of the overall renewable energy sources for the future.Renewable energy accounted for % of total primary energy consumption and % of the domestically produced electricity in the United States in Hydroelectric power is currently the largest producer of renewable electricity in the country, generating around % of the nation's total electricity in as well as % of the total renewable electricity generation.
Clean energy can help bring the economy back to life. The United States has an opportunity right now to reduce its dependence on foreign oil by adopting clean-energy and global warming pollution reduction policies that would spur economic recovery and long-term sustainable growth.
Today, fossil fuel industries drill or mine for these energy sources, burn them to produce electricity, or refine them for use as fuel for heating or transportation.
Over the past 20 years, nearly three-fourths of human-caused emissions came from the burning of fossil fuels. "Consequently, the [United States] is importing decreasing amounts of these two fossil fuels, while using rising levels of its natural gas for power generation," the report states.
