- 1how has the worlds population changed over the last 100 years?it has increased rapidly
- 2give evidence of the change in world populationin 1916 the global population was just under 2 billion, in 2011 it reached 7 billion.
- 3how does population growth affect the demand for energy?it results in a great increase in demand for energy
- 4the population of the world is becoming increasingly wealthy, which has enabled people to afford technology that requires energy. give examples to support this.100 years ago very few people had cars, people heated their homes with coal and only heated part of the house. today, most families in developed countries have two cars and central heating throughout their homes
- 5why are people in emerging countries now using more energy?they are becoming wealthier, meaning they can afford products that need more energy.
- 6the increased wealth in the world has allowed the development of new energy sources and has therefore increased the supply of energy. it has paid for the development of new technology to search out for, and extract, new reserves of energy to provide for the increase in demand. give an example to support this.new reserves of oil and gas were discovered under the sea bed in places such as the North Sea.
- 7new technological advances have allowed a move away from traditional fossil fuels. what types of energy are we now using?renewable. for example wind, water and solar energy
- 8identify a positive impact of developing non-renewable energy resources on people.coal is a cheap form of energy for heating homes
- 9identify another positive impact of developing non-renewable energy resources on people.many jobs are created. for example, the coal mines in south wales in the 19th century and during the development of the North Sea gas in the twentieth century.
- 10identify a negative impact of developing non-renewable energy resources on the environment.greenhouse gases are emitted when gas, coal and oil are burnt.
- 11identify a negative impact of developing non-renewable energy resources on the environment.acid rain is formed from the sulphur dioxide and nitrogen that is given off when coal is burned. this can damage plants and animals around the world.
- 12identify a positive impact of developing non-renewable energy resources on the environment.uranium is a very powerful fuel so only a small amount is needed. this means it produces less CO2 than burning fossil fuels.
- 13identify a positive impact of developing renewable energy resources on people.home owners can have their own wind turbines and solar panels so will benefit directly from 'free' energy
- 14identify another positive impact of developing renewable energy resources on people.solar energy is a growing industry, creating many hundreds of thousands of jobs around the world.
- 15identify a negative impact of developing renewable energy resources on people.wind and solar farms can be unsightly; many people see them as visually intrusive.
- 16identify a positive impact of developing renewable energy resources on the environment.the electricity generated by wind turbines, solar panels and hydro-electric power does not produce any CO2.
- 17identify a negative impact of developing renewable energy resources on the environment.offshore wind farms can affect the migration pattern of birds and wind turbines do kill a number of birds every year.
- 18identify another negative impact of developing renewable energy resources on the environment.the construction of dams for hydro-electric power can destroy large areas of forests.
- 19what is fracking?the process of drilling down into earth to a gas-bearing rock. water, sand and chemicals are blasted at the rock at high pressure which releases the gas inside the rock layers. the gas the flows out the top of the well
- 20how could fracking resolve energy shortages?geologists estimate we could extract enough shale gas from the rocks underneath parts of north-west England to provide energy for 70 years.
- 21at present rates for consumption, when will the UK run out of its own supplies of oil?4.5 years
