From the power plant to the plug - Electricity generation

What is the primary source of energy for electricity generation in a coal-fired power plant?

• Solar

• Coal

• Natural gas

• Wind

What is the function of a turbine in electricity generation?

• To provide lighting for the power plant

• To store excess electricity for later use

• To cool down the electricity before distribution

• To convert the kinetic energy of a moving fluid into mechanical energy for electricity generation.

What is the role of a generator in electricity generation?

• To produce three-phase AC power

• To control the flow of electricity

• To store electrical energy

• To convert electrical energy into mechanical energy

What happens in the transmission substation?

• Large transformers step up the voltage to reduce energy loss

• The turbine drives the transformers

• Large transformers step down the voltage to reduce energy loss

• Aluminum wire is spun round a core of high strength steel

What are the environmental impacts of electricity generation from fossil fuels?

• Decreased water usage

• Increased biodiversity

• Reduced air pollution

• Air pollution, water pollution, and greenhouse gas emissions

How does a nuclear power plant generate electricity?

• Nuclear fission

• Burning coal

• Solar energy

• Wind power

What are the advantages of using renewable energy sources for electricity generation?

• Less sustainable and environmentally friendly

• Higher operating costs

• Increased greenhouse gas emissions

• Advantages of using renewable energy sources for electricity generation include sustainability, environmental friendliness, reduced greenhouse gas emissions, decreased reliance on fossil fuels, and lower operating costs.

What is the process of electricity generation in a wind turbine?

• Solar panels converting sunlight into electricity

• Nuclear fission creating energy through a chain reaction

• Burning of coal to heat water and produce steam

• Rotation of the turbine's blades turning a generator

Which of these are correct with regards to the poles?

• If you live in the countryside, the cables will often be suspended on poles

• If you live in a town, the electricity to your house will be transmitted to your house through an underground cable

What are the challenges faced in integrating renewable energy sources into the electricity grid?

• Lack of government support

• High cost of renewable energy technologies
