source. The source may be electricity or fossil fuel but it is clear that everything needs an energy source to run. In the old days firewood was the energy source. After the invention of automobiles and airplanes in early 20th century‚ fossil fuels have been the most prominent source of energy. Fossil fuels fulfill most of the energy requirement of the world because of which energy produced from other sources are regarded as alternative energy. Fossil fuels are found in a limited amount which puts

In current society‚ the problem of the climate issue and of the finite nature of fossil energy sources is becoming increasingly serious. The need of renewable and clean energy becomes extremely urgent. But in the meantime‚ solar energy as new type energy cause people concern. In addition‚ whether using solar energy to protect environment

SOLAR TREES In modern days the use of non renewable resources is being a major part of lab works. There are different types in these sources‚ but the utilization of them is must. In an age of global concern for escalating fossil fuel prices‚ energy security and CO2 emissions‚ a fervent demand for sustainable energy sources endures. In apt response to this critical issue‚ a renewable alternative energy innovation is receiving wide spread interest and attention. Hence the development

Fossil fuel unfortunately is a non-renewable energy resource and it is completely unsustainable. The population in the United States alone is expected to more than double by 2050.What are we to do about our future energy demand? One of the answers to this fuel problem is bio-fuels. However‚ most of bio-fuels today are produced from the land and we will need all the land we can just in order for us

power plants are being built‚ but most of the new plants still use the same technology as their predecessors. Some have even been ‘repackaged’ to appear cleaner in respect to exhaust‚ but they still pollute the atmosphere and use a dwindling source of fuel. Still others argue that fields of petroleum at deeper levels are more than sufficient to supply the world with oil1. The only real hope of the world is to either perfect some of the newer‚ greener power generation techniques such as wind‚ solar‚ or

Renewable energy sources like wind turbines and tidal barrages are better for the environment than nuclear power and fossil fuels. They also have the potential to last forever. So why are they not being used all over the world? A reason for this is because switching to renewable energy as a primary source would cost a lot of money. Some countries don’t think it is worth it‚ and others simply can’t afford to. There are also many nations that earn a vast amount of money from oil and coal‚ that wouldn’t

reduce global warming by decreasing the amount of coal that is burned which further allows us to reline on the electric roads. "Everyone has power. No more power shortages‚ no more roaming power outages‚ no more need to burn coal. Less need for fossil fuels and less dependency upon foreign oil and much less pollution (solar roadways)". This proves that it reduces global warming because if we install these electric roads we wouldn’t need to burn as much coal as we do now. You ask why? Well the roads
