Energy Resources

Biofuels
1. Renewable
2. Can release greenhouse gasses- but if its used as a methane gas fuel (rural India there is little GHG emmision
Coal
1. Non renewable
2. Top 3 countries with coal reserves
  1. USA - 267,554 mil tonnes
  2. Russia - 173,074 mil tonnes
  3. China - 126,215 mil tonnes
3. Deep/opencast mining = environmental damage
4. GHG from burning
5. Heavy/bulky to transport = more GHG emissions
Geothermal
1. Renewable
2. Large scale use limited to volcanic areas e.g. Iceland
  1. Risk of eruptions and earthquakes
  2. Risk of emissions of sulphuric gases
3. Top producers: USA, Indonesia, Philippines
4. Top Users: China, Iceland, USA
  1. China and Iceland produce their own GT energy
5. Cost effective and reliable
6. Land surface may shrink due to the removal of geothermal resivoirs
Natural Gas
1. Non renewable
2. Middle east is rich in natural gas
3. Russia has largest stores with 47,820 billion cubic metres
Hydroelecricity
1. Renewable + Recyclable
2. HEP is one of the largest of the traditional 5 major sources of energy
3. China, Canada, Brazil, and the USA account for 47% of global HEP generation
4. Top producers: Canada, China, Russia
5. Dependant on precipitation
6. 63.9% of Norways power is HEP
Nuclear
1. Recyclable
2. Australia has the most uranium reserves with 460,000 tonnes. This is followed closely by Canada
Oil
1. Non renewable
2. The Middle East is rich in oil reserves as the top 5 countries with oil lie there
  1. Saudi Arabia
Solar
1. Renewable
2. Large areas of land need to be covered to make good use of it
3. Japan, Germany and, the USA dominate solar energy production
4. Largest photovoltaic plant is in Mojave Desert, California
Wind
1. Renewable
2. 0.8% of world energy supply
3. Germany produce 23.6% of global capacity
Tidal/Wave
1. Renewable
2. Barrages built to harness tidal power destroy wildlife habitats both upstream and down stream
