Energy management and changes in energy

Energy management and changes in energy

What changes were made to energy supply from 1961 to 2007?

↳ 1961- coal contributes 80%

↳ 1974- OPEC quadrupled the price of oil

↳ 1975- develop North sea oil and gas

↳ 1984 to 85- coal miners on strike (30% decrease)

↳ 1990s- Eu’s gas burn rules ended

↳ So natural gas increased rapidly

↳ 2000s- EU and UN limits on carbon emision

↳ So decrease in fossil fuels

↳ 2007- Plans to build a nuclear power reactor

What were the change in energy demand since 1950?

↳ 1950 to 2000- higher energy demand due to growing population (tv)

↳ 2003-energy consumption decreased as energy cost rised

↳ Goverment plan to improve housing insulation,improve boiler standards and enviromental awareness means less energy is used

What is sustainable energy?

↳ Providing energy whilst ensuring it’s long term availability

What plans were made to encourage an increase in sustainable energy?

↳ 2020-plan to increase contributions of renewable energy by 15%

↳ Encourage energy saving and conservation

↳ Goverment insulation plan and labelling eletrical appliances

How is anerobic digestion used and where is it getting used?

↳ Siloth,Cumbria

↳ Storing farm slurry (animal waste) and silage (unused crops) underground

↳ As bacteria breaks it down methane is released and can generate energy for 4,000 homes

↳ Left over liquid can be used as fertiliser

↳ However it cost £4 million

Is there still place for natural gas?

↳ Relatively reliable as we have a North sea supplier

↳ And can import it too

↳ Frackling might be used but due to controversy not yet

Is there still place for nuclear energy?

↳ Most nuclear reactors are coming to an end of usability

↳ Nuclear reactors are expensive but give reliable and efficient energy

↳ Eg-Hinkley Point C (Somerset

↳ Total construction costs are £18 billion

↳ China agreed to 1/3 of the construction costs of a new reactor (£6 billion)

↳ It will run by EDF and expected to run by 2025

↳ Expected to power 5 million homes

↳ Expected to create 25,000 jobs
