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.

Premium Review Tidal Power is the way forward (1300 words)

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

Premium Review Alternative energy sources: Viable options for energy? I think not. (641 words)

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

Premium Review Tidal is the way to go (184 words)

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

Premium Review Alternative energy sources: Save the world with wind turbines! I think not! (460 words)

The politicians are always saying that wind farms will save our planet. What a load of old rubbish. Do they not realise that the wind doesn't always blow and that because of this is doesn't provide a constant supply of energy. Well it doesn't and therefore the power stations fired by coal etc. can never be shut down. They take hours sometimes even days to fire themselves back up again. It's not just a matter of a man hovering above a red button waiting for when the wind stops and then pressing it to give us instant power. No we'd have to spend long periods of time without power until the turbines powered by the traditional fossil fuels were back on line. ...  Read the complete review
