Keeping the lights and heat on

          The options for guaranteeing the UK's energy supply for the future was the topic for Graham Goodeve's talk at Pembrokeshire South East Energy Group's meeting last Thursday.

          The Government, the fossil fuel industry and renewable energy groups are all looking to the resources that will be needed to provide for the ever increasing demand. Edward Davey, Secretary of State at the Department of Energy and Climate Change, has confirmed that we will need a mix of resources.

          Coal is the largest resource of fossil fuel. This creates CO2 emissions (a potent contributor to global warming) and there is currently no proven system of storing them - and if stored underground will they stay there?

          Known reserves for gas and oil are 60 years and 50 years respectively at the current level of consumption. However there is ever increasing demand. Ten years ago ago the UK was an exporter of energy and now it imports a quarter of our needs with gas coming from Norway, Qatar and the Netherlands.

          Graham stressed the need to develop our own resources. We currently produce some oil and gas from shale. The new fracking technique is very contentious and as members discussed is only a way of delaying facing up to climate change. It was pointed out that America is a big, sparsely populated country and the gas cannot be readily exported unlike here where it will be bought by the highest bidder.

          Nuclear power stations are currently being phased out. Agreement has not yet been reached over new ones and they will not come on stream for many years. The problems with dealing with decommissioning and waste have not yet been solved.

          Fusion is the ultimate answer and work is underway but again could be 30 years down the line.

          Renewables could make a huge contribution. We are a windy island surrounded by sea. These forces are infinite. Tidal energy is proven with examples from around the world. The Severn Estuary has the second largest tidal range in the world. There are various options that could be used to capture the energy which could be equivalent to five nuclear power stations!

          Hydro electricity is being used in both large and small scale projects such as at Dinorwig and in the Brecon Beacons.

          Capturing the energy from wind is again a proven technology used widely around the world. One day in December last year it hit a high of 12.2% in the UK. In 2012 it contributed 8,445 MW (8%) of our electricity. Most production is offshore. It doesn't restrict smaller crafts and marine life thrives.

          Geothermal is a huge resource available 24 hours a day. It could produce 20% of the UK's energy needs. There are 'hotspots' around the UK. In Cornwall it is used to heat the Eden Project plus 5,000 homes. In Hampshire it is used to heat public buildings. Oriel y Parc at St Davids uses it to heat the gallery and visitor centre. It can also be used domestically to heat individual homes.

          The power of the sun can be captured for heating hot water in the home, schools or business premises. Photo voltaic cells generate electricity. This again can be small scale or solar farms such as at Rhos-y-gilwern.

          Graham wondered why we were importing wood for biomass burning when we could re-forest areas such as the Heads of the Valley and other former coal ming areas. Trees were a large part of the landscape in the past and now there is only 5% cover. It would create employment in managing them and provide for greater biodiversity.

          All the renewable sources are available and do not endanger our children's future. Also they are free.

          Graham was thanked by the Chair for an extremely informative evening pointing out that we could pursue this topic well into the night.
