Renewable Energy

Question 1

Renewable energy

Answer 1

Energy which is collected from resources which are not going to run out in human timescale

Question 2

Wind energy

Answer 2

form of renewable energy where wind turbines convert kinetic energy into mechanical power and eventually electricity

Question 3

Biofuels

Answer 3

Fuel that comes from a living matter e.g plant source

Question 4

solar energy

Answer 4

the suns energy exploited by solar panels, collectors or cells to heat, water or air or to generate electricity

Question 5

Solar Power

Answer 5

parabolic troughs: Heats liquid to above 400 degrees which is used to turn water into steam which drives the turbine to create electricity
Photovoltaic cells convert suns energy directly into electricity

Question 6

Benefits of solar power

Answer 6

😂Non polluting technology that doesn’t produce noise or greenhouse gases. Causes some pollution but less than burning fossil fuels
😂 Once established sonar panels are cheap to run and maintain
😂 Increases fuel security in countries with adequate sun light

Question 7

Disadvantages of solar panels

Answer 7

😂 Electricity cannot be created when there is no sunlight

😂 Even more efficient photovoltaic cells convert only 20% of suns energy to electricity
