Energy production in Finland made by Ira-Julia, Lassi and Ella

Some basic info

● Energy consumption in Finland per capita is the highest in the European Union

● the most important energy sources arefirewood, oil and nuclear power

● our goal is that we will cut down our consumption and especially carbon emissions

Hydropower

● source of energy where water turns into electricity with water turbines

● the oldest way to produce energy after fire

● about 250 hydroelectricplants in Finland

● our first power plant toTampere on September 22nd 1891

pros and cons?

+ renewable

+ does not cause any emissions

+ water can be stored in huge poolsin big portions

+ possible to prevent floods

- can affect on different fish populations

- weather can affect on its availability

The future of hydropower in Finland?

● Finland is the land of thousand lakes

● there are more pros than cons

Wind power

● source of energy where wind's kinetic energy is transformed into electricity with wind turbines

● at the end of 2014, there were 260 installed wind turbine generators

● wind power production is the highestin the winter months

● especially suitable at coasts nearby the sea

pros and cons?

+ renewable

+ available on every season

+ does not cause waste to ground, water or to the atmosphere

- ruins landscapes

- causes health problems to people who live nearby the wind turbines

- can affect on birds behavior

The future of wind power in Finland?

● possible here but not the best one

● pros are still better than cons because we need to think our carbon footprint

Nuclear power- Nuclear reactions release nuclear energy that generates heat. Nuclear energy

is usually used in steam turbines to produce electricity in power plants.- Nuclear power plants provided 17 percent of the world’s electricity production

in 2015.- There are many arguments for and against nuclear power, but overall the

future of nuclear power looks promising.

Pros in nuclear energy

+ Nuclear energy is relatively cheap form of energy, especially compared to renewable energy sources.

+ Nuclear power plants provide a stable base load of energy.+ The pollution coming from nuclear energy is minimal. However nuclear waste

is harmful for both humans and environment.+ Countries that use nuclear energy have still enough uranium for

approximately 80 years on average+ The amount of energy released in a nuclear fission is ten million times greater

than the amount released in burning a fossil atom.

cons in nuclear energy

- accidents happen. Radioactive waste is toxic for humans and environment. (Chernobyl accident)

- Nuclear power plants causes very minimal if any air pollution. However the process in the nuclear fuel chain such as mining and enrichment does cause pollution.

The future of nuclear energy

- There are a lot mixed feelings about the future of nuclear energy.

- Some experts say that nuclear and fossil based energy will be replaced by renewable energy sources in approximately 30 years, but majority of experts say that nuclear energy will stay at it is for quite a long time or the usage of it will decrease just a tiny bit.

- many experts say that nuclear energy is one of the best if not the best form of energy production when the costs and the amount of pollution are considered.

- Some countries like France, Spain and Italy are planning to close few power plants. They are considered to be too dangerous as a working environment.

Nuclear energy in Finland

- There are four power plants in Finland. These four power plants produce approximately one fourth of the electricity in Finland.

- Two power plants are currently being constructed and the owner companies (Fennovoima, Teollisuuden voima) have stated that these power plants will begin to produce electricity in years 2018 and 2020.

- Majority of Finns support nuclear energy. In fact over 60 percent of finns that answered to the inquiry supported the growth of nuclear energy in Finland.

- The portion of energy that is produced by power plants will grow considerably when the power plants currently being constructed are producing electricity.

Heating of a one-family house...Today:

- electricity (straight electric, district heating

- oil

- ground heat

- wood pellets

With: wood heat or air/water heat pumps

New one-family houses:

- 45% ground heat power

- 27 % electricity

Energy certificate for buildings- Since 2008

- The law 2013

Why:

- to count the using of energy of new houses 20%

- to move towards zero-energy buildings

- to achieve the climate objectives

Buildings do matter

The energy consumption of buildings causes over one third of the greenhouse gas emissions in Finland.

We have to do and we are able to do eco-efficient solutions to cut down greenhouse gas emissions.

Pros and cons...

The coefficient of straight electricity is 1,7.

Fossil fuels: 1.

District electric: 0,7.

Renewable fuels: 0,5.

Solar energy: ~0

- cheap when investing and easy to use but expensive when used a lot

- easy to use but effects on climate change

- quite cheap to invest but not the cheapest one to use

- (wood pellets): domestic but needs work, burning makes also fine particle emissions

- great for climate but unstable in Finland

Ground heat/ geothermal power: expensive when investing and not available to everywhere, uses electricity but clearly less than straight electric heating
