Disadvantages of energy resources

• Fuel: Harmful wastes (Greenhouse/ pollutant gas, Radiation)
• Wave energy: Difficult to build
• Tidal energy: Expensive, Can’t be built everywhere
• Hydroelectric: Few areas of the world suitable
• Geothermal: Deep drilling difficult and expensive
• Nuclear fission: Produces radioactive waste
• Wind: Few areas of the world suitable.
• Solar cells/ photovoltaic cells: Variable amount of sunshine in some countries
