Lesson 15 the uk energy mix Flashcards
UK has abundant resources for what
up until the 1950s almost all of the electricity generated in the UK came from ________ ____
coal
burning coal
in the1950s nuclear power came online and by what time did it produce 20% of the UKs electricity
1980s
in the 1970s, UK became a major producer of oil and gas from the north sea and this began to replace _____
coal for electricity generation
by 2000, as much electricity was generated from _______ as from _____
burning gas as from coal
producing electricity from coal to gas has 2 major benefits from using coal
burning gas generates less CO₂ than burning coal(contributes less to climate change)
gas fired power stations are flexible (can be switched on quickly during high demands as they have a short start up time whereas coal-fired power stations have a very long start up time)
in the 1970s scientists realised that CO₂ emissions from human activity could be leading to ________ ____
climate change
in 2005 a large number of nations signed to the Kyoto protocol
which did what?
committed countries to reducing greenhouse gas emissions
the problems with renewables are reliability and this can be fixed via……
needing a baseload (nuclear power is ideal)
using gas fired power stations (this provides emergency energy in in times of peak demand)
coal and coal gas were used for almost all the what for the UK
the heating and cooking
energy from fossil fuels was very cheap which was known as an
economic factor
switching away from fossil fuels costs money which could cost what
jobs
UK has got one of the best locations for what in the world
wind-power
over the last decade, the UK has opened a large number of what
wind-farms
in the future renewables will provide the bulk of our what
electricity, with nuclear providing our baseload and then the gas producing electricity during periods of peak demands
