Consuming Energy Resources Flashcards
Name the 3 categories of energy resources
Renewable, Non-renewable and recyclable.
Name some ways of producing energy that damage the environment
Mining, habitats get destroyed and Drilling oil spills into oceans
What are some negatives of wind energy?
Take up lots of space, constant humming noisy and the blades can kill or injure birds or bats
What are some negatives of solar energy?
Heat reflected from mirrors can kill wildlife
Not reliable in areas with little sun
What are some negatives of Hydro Electric power?
Cause other issues e.g. flooding further downstream and they are very expensive to build. Also requiring lots of water and land.
What factors have an impact on a country’s access to energy?
Technology, geology, accessibility (permafrost), climate and landscape.
Why do developing countries use very little energy?
As they have more primary industry e.g. agriculture which uses very little energy.
What can oil supply and oil prices be affected by?
conflicts, diplomatic relations, recessions (lower demand) and economic booms (higher demand so prices increase)
Give examples of an oil reserve and unconventional gas
Tar Sands and fracking
Why is fracking bad for the environment?
It pollutes groundwater and drinking water due to the chemicals used.
Why are Tar sands bad for the environment?
Liquid waste is produced which is full of harmful chemicals which can pollute water supplies if not managed properly.
Also the vast amount of space needed devastates habitats.
In what ways can the demand for energy be reduced?
By conserving energy and making energy use more efficient.
What is energy conservation?
Changing our behaviour e.g. driving less, and drying our clothes on a line rather than using a dryer.
What is energy efficiency?
If something is energy efficient it does the same job but using less energy. e.g. low-energy lightbulb
Where are two areas where the demand for energy can be effectively reduced?
The Home and Transport
How can the demand for energy be reduced in the two areas?
Insulation, solar panels - HOME
Improving public transport or encouraging walking
Hybrid cars combine diesel and electric power to increase efficiency. They use electricity hen possible and recharge their batteries using diesel power.
What are the 3 main advantages to reducing the use of fossil fuels
Improving energy security (having a reliable and affordable supply of energy available)
Reducing carbon footprint
Diversifying the energy mix
