There is no simple answer to the problem of our future energy resource. Wind, wave, tidal, solar, biogas, etc, are all perfectly viable and proven technologies, but none of these in isolation or even combined has the potential to come even close to replacing our current energy requirement. Each has its own advantages, and its disadvantages. But there is no 'one size fits all' and there never will be. Each has it's 'knockers' - the NIMBY's, the 'such & such is highly inefficient / not cost effective', etc. But we have to learn to accept that, though none alone can currently contribute in any significant proportion, we cannot simply dismiss them ...  Read the complete review

Renewable energy, wether we like it or not, is what we will have to rely on. Wind power at the moment is not profitable, it costs too much to build and maintain wind turbines, and they do not pay back enough. Tidal power is good, if you can get permission to build a damn in some of the biggest river mouths of your country. Geothermal and hydroelectric power are the best alternative energy sources. Geothermal is taking the earth's heat to generate energy, the trouble with it is that the earth's heat is only accessible in some areas, mainly ones with volcanic activity. Hydroelectric is a reliable method of power generation, but again, is ...  Read the complete review

The Planet is currently in a delicate state in its development, Human impact has had obvious affects. In 2005 the UK consumed, on average 1.82 million barrels of oil per day. At a conference last year, Exxon Mobil and Shell predicted that wind and solar power combined would account for just 1% of global energy demand by 2030. If they're correct, fossil fuels will remain the dominant energy source, which can not occur without consequences considering the environmental impacts and the levels of fossil fuels left available to man. This outlines the fact we must make a move now, before it's too late. I have recently completed my first year at university, studying ...  Read the complete review

Now, there are many "viable" sources of energy that is renewable and very environmentally friendly. Ideas being thrown around as well as executed include wind power, solar power, tidal power, biomass energy, geothermal energy and hydroelectric power. To be honest, not many of these options are really viable. Wind power at the moment is no where near efficient enough, considering it takes hundreds of wind turbines to generate enough power to heat a medium sized village. If the UK turned to wind power as it's sole source of energy no-one would be able to reach the sea for a seemingly singular mass of wind turbines. So that's a no. Solar ...  Read the complete review

Wind power, no. Solar power, No. The answer is simple and yet effective, tidal power. What we need to do is bulid a tidal blockage across the river severn, this would provide lots of energy. The way that this would occur is by slowly letting the water out as it goes from high tide to low tide, using propellers to generate the energy, and when the water rises back you just let it through. Also this would enable you to have solar and wind power as well as it would not matter as much if it isnt windy. The positioning of the wind turbines should be not inland but offshore. The reason for this is that they will generate more energy than when they are inshore. ...  Read the complete review
