ENERGY RESOURCES

ENERGY

-it powers everything from homes and industries to transportations and communication

-it is classified into renewable and non renewable energy sources

Renewable Energy

-comes from natural sources

-can replenish themselves over short periods

-has lower environmental impact

Solar energy

Wind energy

Hydropower (Hydrolectric Energy)

Geothermal Energy

Biomass Energy

examples of renewable energy

Solar Energy

-one of the most abundant and clean energy sources

-harnesses sunlight to generate electricity/ heat

-Infinite and Abundant Source

-Environmentally friendly

-Low operating costs

Advantages of Solar Energy

-Dependent on sunlight availability

-High initial installation cost

-Requires large areas for solar farms

Disadvantages of Solar Energy

Wind Energy

-it uses air movement to generate electricity through wind turbines

-Renewable and abundant in windy areas

-No greenshouse gas emissions

-Low operational cost

-Advantages of Wind Energy

Hydropower (Hydroelectric Energy)

-it uses moving water to generate electricity

Geothermal Energy

-it taps into heat from the Earth’s interior to generate electricity/ provide direct heating

-Minimal Greenhouse gas emissions

Advantage of Geothermal Energy

Biomass Energy

-it uses organic materials to produce energy

Reduces Waste by repurposing organic materials

Advantage of Biomass Energy

Non-Renewable Energy

-it is finite and it takes million years to form

-it contributes significantly o environmental pollution and climate change

-Fossil Fuels

-Nuclear Energy

Examples of Non Renewable Energy

Fossil Fuels

-such as coal, oil, natural gas

-most widely used energy sources

Coal

it is burned to produce steam

Oil (Petroleum)

-it is fuel for transportation and industry

Natural gas

-it is burnedo generate electricity heat

-Cleaner than coal and oil

Nuclear Energy

-it generates energy through nuclear fission, where atomic nuclei split to release energy

Energy Conservation Strategies

-it is reducing energy consumption through efficient usage and behavioral changes

Efficient Appliances

- t is using LED bulbs

Transportation Efficiency

-using of electric vehicles

Building Insulation

-it is reducing energy loss in homes

Industrial Optimization

it is implementing energy efficient proven in factories
