Sustainable Energy Solutions for the Future
The world energy problem
and ways to solve it
Fyodor Malchik
The Energy crisis
We are running out of energy.
We need think about how we will make
energy in the future.
Imagine you were running the
country. What types of energy
would you use?
Wind, sea, nuclear, solar, coal?
Look at the different types of energy
then discuss your choices.
Wind power
Onshore wind power has the
potential to provide a valuable
income for rural Wales,
particularly to farmland
communities in upland areas.
Sea power
The sea around the Welsh coast has the
potential to generate large amounts of
electricity by harnessing the power of the
tides, currents and Waves. Wales has strong sea
currents and some of the highest tidal ranges
in the world.
Plans are being discussed for Swansea Bay, Severn
Estuary and Liverpool Bay.
Nuclear power
There are currently 16 nuclear
power plants in Britain – all will
close by 2023.
The idea is that other renewable energy sources
will replace nuclear power production and
relieve Britain's reliance on fossil-fuels.
However, the government is currently being
advised to build further nuclear power stations
if they are to meet greenhouse gas emission
targets.
This picture shows Trawsfynydd nuclear power station in the
Snowdonia National Park. It closed in 1993. The nuclear
reactors are still held within the building.
Solar power
Solar roof tiles use light from the sun
to create electricity or hot water.
Houses with lots of tiles could
generate more electricity than they
use – this could be sold back to local
electricity companies.
Coal, gas and oil.
Oil experts estimate that we will use
all our oil reserves within the next 40
years! Others say we will find more.
Sun tubes
Sun tubes reflect natural daylight down
through a tube into a home or office. They
are a great way to save energy during the
day.

The world is facing an energy crisis, and it is crucial to consider alternative sources of energy for a sustainable future. Options such as wind power, sea power, nuclear energy, and solar power are being explored, each with its advantages and disadvantages. Decision-makers must weigh these factors to choose the most suitable energy mix for a country. Embracing renewable energy technologies is essential to reduce reliance on fossil fuels and combat environmental challenges.

The world energy problem and ways to solve it Fyodor Malchik
The Energy crisis We are running out of energy. We need think about how we will make energy in the future.
Imagine you were running the country. What types of energy would you use? Wind, sea, nuclear, solar, coal? Look at the different types of energy then discuss your choices.
Wind power Onshore wind power has the potential to provide a valuable income for rural Wales, particularly to farmland communities in upland areas. Advantages Disadvantages Renewable. Non-polluting. A well proven technology. Does not produce power when the wind isn't blowing. Local residents are often against development as it changes the local landscape.
Sea power The sea around the Welsh coast has the potential to generate large amounts of electricity by harnessing the power of the tides, currents and Waves. Wales has strong sea currents and some of the highest tidal ranges in the world. Plans are being discussed for Swansea Bay, Severn Estuary and Liverpool Bay. Advantages Disadvantages Renewable. Non-polluting. Relatively new technology. Local residents are often against development as it changes the local landscape.

The idea is that other renewable energy sources will replace nuclear power production and relieve Britain's reliance on fossil-fuels. However, the government is currently being advised to build further nuclear power stations if they are to meet greenhouse gas emission targets. This picture shows Trawsfynydd nuclear power station in the Snowdonia National Park. It closed in 1993. The nuclear reactors are still held within the building. Advantages Relatively cheap to make. Disadvantages Nuclear power produces toxic radioactive waste which will last for tens and thousands of years. Does not contribute to the greenhouse effect. Nuclear power stations and the trains, lorries and ships that transport nuclear fuel waste could be an easy and devastating target for terrorists. Produces huge amounts of energy from small amounts of fuel.
Solar power Solar roof tiles use light from the sun to create electricity or hot water. Houses with lots of tiles could generate more electricity than they use this could be sold back to local electricity companies. Advantages It is a well proven technology. Well suited to providing power in home or single building applications. Renewable. Disadvantages They are expensive to buy. Making them requires a lot of energy.
Coal, gas and oil. Oil experts estimate that we will use all our oil reserves within the next 40 years! Others say we will find more. Advantages Relatively cheap to produce but prices are rising. Disadvantages The resources are running out. Most scientists believe they are heating up our planet. They pollute the air we breath and produce acid rain which damages buildings and crops.
