Go Greener Tips

Against a global backdrop of rocketing oil costs and concerns about climate alter and security of energy supply, interest in renewables has never been more intense. Renewable energy is energy from natural sources – the wind, sun, geothermal, waves and tides, and water – which, unlike fossil fuels, such as coal, gas and oil, will never run out. Moreover renewable energy technologies produce little or no greenhouse gases – the main reason of climate alter. As an example, see the V-Dimension Helius review.

The key issues with renewable energy are how to produce it, turn it into utiliezed energy and deliver it to where it is required. Not renowned for being the sunniest of places, the UK has some of Europe’s best wind power resources and is a world leader in marine power technology. Although wave and tidal power technologies are still in their infancy, the Carbon Trust evaluates that marine power sources could produce up to 15% of the UK’s energy. In May 2008, the world’s first commercial tidal turbine was setteled in Strangford Narrows, Northern Ireland generating power to 1,000 homes. There are also great energy sources from solar power too, such as this Voltaic Messenger Bag review. Just don’t be to excited if you’re not in the sunniest of places.

Growing at a global rate of 30%, wind power is the most mature and cost effectual renewable energy technology: worldwide in 2008 there was 121 GW of settled wind capacity, with the UK accounting for some 4 GW of installed capacity by the end of 2009. Under the EU Renewable Energy Directive, the UK government has signed up to a legally binding target of generating 15% of UK energy from renewables by 2020. This is a seven-fold raise from the 2008 level of just over 2%. Renewable power production in the UK is at a very low level collated to other countries such as Denmark, Spain, Germany and the US. There is a mountain to climb if the 15% target is to be met.

The UK’s Renewable Energy Strategy 2009, published in July 2009, sets out how the government plans to reach its ambitious renewable energy objective. Specific objectives include producing more than 30% of electricity from renewable sources (collated to around 5.5% today), mainly on- and off-shore wind, but also hydro, biomass and marine power technologies. Transport energy from renewables will need to raise from the current 2.6% to 10%, and 12% of heat energy is undertaken to come from sources such as biomass, solar and biogas.

Along with carbon capture and storage technologies, carbon emissions trading, new nuclear potential, and energy saving and efficiency measures, renewable energy is part of the government’s plan to remove the UK to a low-carbon, more self-sufficient energy economy that addresses both climate change and security of supply issues.

If the strategy achieves its objectives, the UK will reduce its carbon dioxide emanations by more than 750 million tonnes between now and 2030. Fossil fuel consumption will lessen by around 10% and gas imports by 20-30% by 2020. The tactics foretells that achieving the targets could make half a million jobs in the renewable energy sector by 2020, and leverage £100 billion worth of investment opportunities.
