Mitigation strategies and effectiveness Flashcards
How much of UK energy consumption does domestic energy demand take up
1/3
What could energy efficient homes do in the UK
reduce carbon emissions by 500 mil tonnes per year
How can homes be more energy efficient
Insulation
Solar panels
South facing windows
Conserving energy
How is the UK aiming to insulate - current scheme +drawbacks
£1bil grant for home insulation - aim for 300,000 homes per year
But this would take 200 years to insulate all the homes in need of upgrades - 19mil homes
Example of an eco-village and how energy efficiency can work
BedZED - UK’s largest eco-village - 100 homes
Well insulated, thick walls, solar panels, South facing windows, grey water system
Means it is carbon neutral - produces as much carbon as it uses
How much do Fossil Fuels contribute to US total emissions/year
75% of US GHG emissions
Improvements in UK Fossil fuels vs renewables energy stock
FFs - 80% 2013 - 32% 2020
Renewables - 15% 2013 - 32% 2020
Why is nuclear good and current global nuclear use
Less CO2 produced than renewables
15% global energy stock
But uranium unrenewable
UK nuclear aims
To increase nuclear by 25GW by 2050
Opening 2 new nuclear plants
China solar
Produce a third of the world’s solar energy
Spain solar
Previously the largest producer of solar energy
Andosol Wind farm - energy for 500,000 people
UK wind farms
UK most renewables are wind farms
London Array wind farm - produces energy for 750,000 people
Iceland renewables
100% renewables
mostly hydroelectric and geothermal
Why is coal still significant/can it be significant
Coal very dirty - reducing it is significant
China and India still have high coal use
Definition of CCS
Extracting CO2 from its emission from factories/power stations, transferring it to facilities and storing it
