Can Alternative Energy Effectively Replace Fossil Fuels?

The alternative energy sources such as biofuels, solar, geothermal, or nuclear energy can meet energy demands better than finite fossil fuels such as oil and coal seems to remain hotly debated. Components of alternative energy argue that fossil fuels are inefficient, unsustainable, environmentally destructive, and the primary contributor to global climate change. They say renewable energies are a viable and immediately needed alternative to fossil fuel use that could boost the economy and reduce reliance on foreign energy sources.

Environmentalist contend that many  hurdles have to be overcome before alternative energy can replace even a small portion of the power provided by fossil fuels. They say that fossil fuels will last hundreds of years longer, if made increasingly efficient, remain the most economical choice, and that reliance on inefficient alternative energies will hurt the economy.

This issue has created a variety of different Opinions between experts who try to apply them and some who think otherwise.

Richard Heinberg, MA, research center senior, said It will take at least three decades to completely leave behind fossil fuels, But we can do it. But the transition will need costs—not just money and regulation, but also changes in our behavior and expectations. It will probably take at least three or four decades, and will fundamentally change the way we live. The renewable economy will likely be slower and more local; it will probably be a conserved economy rather than a consumer economy.

This can be taken as a positive response But there are negative viewpoints as well.

Robert Lyman, Principal at Ens Policy Research Group, Inc., stated¬†‚ÄúOil provides 95% of the fuel demands of the transportation sector… ‚Äì cars, trucks, trains, buses, marine vessels, and aircraft ‚Äì relies almost entirely on petroleum fuels and, in recent years as the result of regulated fuel reserve, ethanol – have made small inroads in the share held by oil. Further, on the basis of the projections by all major agencies that analyze energy supply, this will continue to be the case for the far future…

Components of the all-renewable future seem to be stuck in a time warp. Oil prices are still close to $130 per barrel (globally), and natural gas and coal prices are surging. In such a world, it may be easier to make the case that renewables will become far more competitive sooner. The reality, is that the decline of international oil prices to the range of $40 per barrel and the dramatic bend in natural gas and coal prices in many areas (countries) has meant that these fuels are far better placed to compete with alternative energy sources.”

This question has always been a case of debate for the environmentalist and certain sections of the research society are showing interest in vortex of this issue. But, can it happen or will it happen seems to be the case.
