How it works:

1. A nuclear power plant uses the energy from nuclear fission to generate heat, which creates steam to drive turbines that produce electricity. It is an effective way to generate power with relatively low greenhouse gas emissions.

✅ Pros:

1. Low Greenhouse Gas Emissions

2. High Energy Output

3. Reliable and Consistent

4. Reduces Dependence on Fossil Fuels

5. Advanced Technology and Safety Improvements

❌ Cons:

1. Radioactive Waste

2. Risk of Accidents

3. High Initial Costs

4. Nuclear Proliferation Risk – Nuclear technology can be misused for weapons development, increasing geopolitical tensions.

5. Limited Fuel Supply

Use in Austia:

Austria does not use nuclear energy. Instead, it focuses on renewable energy sources. Although Austria has spoken out against the construction of a nuclear power plant in Zwentendorf it still exists. Nuclear power imports to Austria are increasing. In 2014, the share of electricity consumption was even 12 percent.

Renewable: Relies on the water cycle, reducing fossil fuel use.

Low Operating Costs: Cheaper to maintain once built.

Reliable

Long time Operation: Can operate for decades with maintenance.

Disadvantages

Environmental Impact: Affects ecosystems and displaces communities.

High Initial Cost: Expensive to build dams and reservoirs.

Climate Dependent: Droughts and changing rainfall patterns affect water availability.

Use in Austria:

two thirds of power generated in Austria is by Hydropower-Plants

1) Define/Explain

Gas energy is produced by burning natural gas or biogas to generate heat, electricity, or power industrial processes. It’s cleaner than coal or oil but still releases carbon emissions.

2)Pros

High efficiency

Lower Co2 than coal & oil

Flexible use

Well developed infrastructure

3)Cons

Co2 and methane emissions

enviromental risks

Dependence on Imports

Non-renewable (fossil gas)

4) Use in Austria

In Austria, gas energy is widely used for heating, electricity generation, and industrial processes. The country relies on natural gas imports and uses it as a bridge energy source as it transitions to renewable energy.

Coal is not considered as an alternative energy. It is regarded as a traditional fossil fuel.

How it works?

1) The coal is burned to produce heat

2)The heat is used to evaporate water into high pressured steam

3)The steam spins a turbine connected with a generator, which converts mechanical energy into electrical energy

4) the steam cools off, and is reused again

Pro's:

•) it is reliable, because it provides steady electricity

•) Coal is plentiful in many regions

•) it is an old and well known method to generate power

Con's:

•) it contributes to climate change by causing emission and air pollution

•) it is finite because it is not renewable

Nowadays only 9 percent of electric power consumption in Austria is being covered by energy from coal.

Definition / Explain

1. Extraction: Oil is extracted from underground reservoirs using drilling techniques.

2. Transportation: The crude oil is transported to refineries via pipelines, ships, or trucks.

3. Refining: In refineries, crude oil is processed and separated into various products, such as gasoline, diesel, and jet fuel.

4. Distribution: These refined products are then distributed to consumers through pipelines, tankers, and gas stations.

5. Using: Burn the refined oil products to generate energy for transportation, electricity, heating, and industrial processes.

Pros of Oil:

1. Energy Density: Oil has a high energy content, making it efficient for transportation and electricity generation.

2. Economic Growth: The oil industry creates jobs and contributes significantly to the economy, especially in oil-producing regions.

3. Versatility: Oil can be refined into various products, including gasoline, diesel, jet fuel, and petrochemicals used in plastics, fertilizers, and more.

4. Infrastructure: Established global infrastructure supports the extraction, refining, and distribution of oil, ensuring a stable energy supply.

Cons of Oil:

1. Environmental Impact: Burning oil releases greenhouse gases, contributing to climate change and air pollution. Oil spills can cause severe damage to marine and terrestrial ecosystems.

2. Finite Resource: Oil is a non-renewable resource, meaning it will eventually run out. As reserves deplete, extraction becomes more difficult and costly.

3. Geopolitical Tensions: Dependence on oil can lead to political and economic instability, particularly in regions with significant oil reserves. This can result in conflicts and fluctuating prices.

4. Health Risks: Exposure to oil and its byproducts can pose health risks to workers and communities, including respiratory problems and cancer.

Balancing the benefits and drawbacks of oil is crucial as we consider the transition to more sustainable energy sources.

OIL in Austria:

Austria's domestic oil production is limited, so our country is heavily dependet on imports.

With a growing focus on renewable energy, Austria is compelled to reduce its oil consumption.

OIL in Austria is used for:

- Traffic (Cars, Trucks, Airplanes)

- Heating

- Asphalt in road constructions

- Raw material for the chemical industry (e.g. plastic, paints, pharmacy)

No Co2

Tides are regular and reliable

Long life and low costs

Fossil fuels and emissions are significanty reduced

Contra:

High Investment costs

Location dependency

Impact on ecosystem

Technical challenges

In Austria we can Not use it because we have no tides.

Low operating costs: Once installed, turbines are cost-effective.

Job creation: It supports employment in various sectors.

Energy independence: Reduces reliance on fossil fuels.

Scalable: Can be used in small or large projects.

Space efficient: Can be installed without major land disruption.

Cons:

Intermittent: Wind doesn't blow constantly, so wind power generation can fluctuate.

High initial costs: Building wind farms, especially offshore, can be expensive.

Storage challenges: Storing wind energy efficiently is still a work in progress.

Noise pollution: Wind turbines can produce noise, requiring careful planning and distance from residential areas.

Impact on landscape and wildlife: Wind farms can alter the landscape and pose risks to birds and bats.

Use in Austria:

In Austria, wind energy is primarily used in the eastern regions, particularly in areas like Lower Austria, Burgenland, and Styria, where wind conditions are most favorable. Wind energy contributes around 10% to Austria's renewable energy mix, playing a key role in the country’s goal to achieve a sustainable and low-carbon energy system.
