Renewable Energy and Industrial Ecology

E42

You are asked to design an energy strategy to be implemented over the next 25 years.

The energy sector in the UK is historically marked by it’s coal mines, then by oil and natural gas offshore in the North Sea. Nuclear power has also played a significant role and is under recovery. Finally, the United Kingdom for several years has a significant policy incentive for renewable energy in particular wind.

Natural gas: 41%
Coal: 29%
Nuclear: 18%
Renewables: 9%
Other: 2%.
(Department of energy and climate change, 2013)

The UK seeks to achieve in 2020 the share of renewable energy that has been set by the Climate and Energy Package (an action plan adopted on 23 January 2008 by the European Commission), while meeting its energy demand, while some plants reach the end of life. The energy companies are thus committed heavily in the gas, but also (to a lesser extent) in nuclear power. The financing of renewable energy such as offshore wind, however, is not enough.

Recognizing these problems, the government launched an ambitious program that focuses on two pillars and is a real energy revolution. First, it encourages energy companies to invest in ways to lower emissions than traditional coal plants, such as gas plants and wind production. The government has launched a comprehensive reform of the electricity market, which amounts to more regulation (long-term contract for renewable energy and CO2 tax for example). Second, it prepares for the post-2020 accompanying the research in future technologies: CCS and offshore wind in particular (CCS: Carbon capture and storage : He is buried in the basement, massive and securely, carbon previously "captured" boiler outlet or gas turbines and compressed dioxide).

Aware of existing uncertainties beyond 2020, particularly in the cost of technology, the government prefers to build a portfolio of technologies in each sector: renewable energy, nuclear and CCS in the power sector, hybrid electric vehicle, or all-electric fuel cell for transport heat pumps, heating network development, and smart grids for the building. If we focus on the electricity sector in 2038, some 40 to 70 GW of capacity will be built, and the government seeks to encourage the means of low-emission production. Nuclear, renewables (mainly offshore wind and biomass) and CSC are among the key technologies that the government wants to support (UK Government , 2010).

We will try to design our energy strategy to meet UK’s energy needs helping us to that was previously explained: This strategy is focus on maximizing renewable energy use and therefore minimizing non-renewable energy use in the UK.

Firstly we can study one of the most used energy: wind power, offshore wind in particular, why offshore? An offshore wind turbine works the same way as onshore wind, but is located offshore to best use wind energy to produce electricity through a turbine. This country has a large coastline particularly exposed to westerly winds (the first European potential, ahead of France), became the first offshore electricity producer in the world in 2010 with an installed capacity of 1341 MW. And also because by 2015, the park could bring 50 to 100 wind turbines with a unit capacity of 5 10 MW and a total installed capacity of 500 MW. Some facilities "farshore" that is to say off (more than 30 kilometers from the coast), with floating bases, are now in the design phase.

The UK are already very implicated in this production and this action as only just begun because they opened the largest offshore wind farm in the world on July 2013, with enough capacity to power two-thirds of the homes in Kent, the set of 175 turbines rising out of the Thames (Shankleman, 2013). Production costs and...
