3.2 Conservation of Energy - Energy Sources
Non-Renewable Sources
Fossil Fuels
Coal, oil and gas
Gas
+Lower greenhouse emissions
+Quick start up times allow for flexible generations
Coal
+Cost-effective and generation all the time
-Greenhouse emissions
Carbon dioxide
Global warming
Sulfur dioxide
Acid rain
+Large amounts of energy per kg of fuel
Nuclear fuels
-Harmful nuclear waste must be stored for years
-Risk of nuclear disasters
+Large amounts of energy per kg of fuel
+No greenhouse gases
Renewable Sources
Hydroelectricity
+Provides large quantities of energy in a short time (power surges or outages)
-Affects water life
-Only limited number of suitable sites for water dams
Tidal Power
+Renewable and predictable
-Relatively new so costly to install & maintains
Wind Power
+Cost-effective and abundant source of energy
-Restricted by wind speeds
-Visual & Sound Pollution
Bio Fuels
+Quickly & locally grown (renewable)
-Needs a lot of land which could be used for food production
Solar Power
+Relatively cheap, can be used in remote areas
-Only possible in daylight
