key points
energy demand are met mostly by burning oil, coal and gas
nuclear power, biofuels and renewable resources provide energy to generate some the energy we use
uranium of plutonium is used as a fuel in a nuclear power station. much more energy is released per kg that fossil fuels
-
biofuels are renewable are renewable sources of energy. Biofuels such as methane and ethanol can be used to generate energy.
radioactivity
-
3 types
alpha
stopped by paper 2 pro and 2 nev, strongly ionising
-
-
beta
stopped by aluminium, same as an electron, weak ioniser
-
-
-
gamma
reduced by lead, bursts of energy, ionises very weakly
