There are two theories about fossil fuels - either they will never disappear or they will within the next 127 years. Renewable energy sources need to replace fossil fuels. Renewable energy can be obtained from waste through processes like biogas, methane, and biomass. Biomass involves feeding waste into an oven to produce methane which can be burned for electricity, though some argue importing waste raises issues. Nuclear power does not emit carbon but nuclear waste storage risks accidents.

2. • there are two theories about fossil fuels:
a) fossil fuels are abundant and will never
disappear
b) oil supplies wil disapper in 34 years,natural
gas in 55 years and coal for 127 years
• We have to replace fossil fuels with renewable
energy sources
• We can get fuel, biogas and methane from
waste

3. • oil
• coal
• natural gas

4. • wind, water, solar energy

5. Windmills
and solar
panels =
energy from
wind and
sun

6. • Nuclear plants do not emit carbon dioxide, which is
harmful to the environment, but nuclear fuel
becomes radioactive and must be stored for decades
in the security concrete pools.
• If the storage error occurs, an accident of gigantic
proportions like those at Chernobyl in 1986. and
Fucushima 2011. could happen.

8. • Biomass is what most people consider garbage like
trash, garden waste, wood chips and even manure.
• The biomass is fed into a large funnel and then into
the oven where mass burns. As the waste
decomposes, it produces methane, which is
collected in tubes. Methane can be burned in a
power plant to produce electricity.

10. • Fuel produced from paper, wood, textiles and
small plastics under controlled conditions.

11. • Most of you don’t know Sweden is importing
waste from other European countries.
Importing garbage is not a common thing, is
it?
• Swedish have a reason for it, given the modest
production waste, they imported it because
they have an incinerator and operations would
close without imports.
