Energy Efficiency Basics

What are examples of renewable energy sources?

• Coal energy

• Nuclear energy

• Oil energy

• Solar energy, wind energy, hydroelectric power, geothermal energy, biomass

How can energy conservation techniques help reduce energy consumption?

• By optimizing energy usage, reducing waste, and promoting efficient practices.

• By wasting energy, not optimizing usage, and encouraging inefficient practices.

• By increasing energy waste, encouraging inefficient practices, and ignoring optimization techniques.

• By promoting excessive energy usage, neglecting waste reduction, and discouraging efficient practices.

What are the benefits of using efficient appliances?

• Higher energy consumption

• Limited functionality

• Increased maintenance costs

• The benefits of using efficient appliances include lower energy bills, reduced environmental impact, and improved performance.

What are common insulation methods used to improve energy efficiency?

• Adding insulation, sealing air leaks, installing energy-efficient windows and doors, using insulated curtains or blinds

• Not sealing air leaks

• Leaving windows and doors open

• Using more water heaters

What are some renewable energy policies implemented by governments?

• Feed-in tariffs, renewable portfolio standards, tax incentives, grants

• Carbon pricing, nuclear subsidies, coal plant subsidies

Why is solar power considered a renewable energy source?

• Solar power is renewable because it depletes the ozone layer.

• Solar power is considered renewable because it is derived from the sun, which is an abundant and virtually inexhaustible source of energy.

• Solar power is renewable because it relies on wind energy.

• Solar power is renewable because it comes from burning fossil fuels.

Explain how LED light bulbs are more energy-efficient than incandescent bulbs.

• LED bulbs emit more heat than incandescent bulbs, making them less energy-efficient.

• LED bulbs convert more electricity into light rather than heat, making them more energy-efficient.

• LED bulbs require more electricity to produce the same amount of light as incandescent bulbs.

• LED bulbs have a shorter lifespan than incandescent bulbs, resulting in higher energy consumption.

What is the purpose of weatherstripping in energy conservation?

• To seal gaps around doors and windows, preventing air leaks and improving insulation.

• To increase the noise level inside the building

• To provide a decorative element to doors and windows

• To attract more sunlight into the building

How does geothermal energy contribute to energy efficiency?

• Geothermal energy increases greenhouse gas emissions

• Geothermal energy is not a renewable source

• Geothermal energy depletes natural resources

• Geothermal energy reduces reliance on fossil fuels and increases energy efficiency by utilizing heat from the Earth's core.

What role does energy star rating play in choosing efficient appliances?

• Energy Star rating has no impact on appliance efficiency

• Energy Star rating indicates the color of the appliance

• Energy Star rating measures the weight of the appliance

• Energy Star rating plays a crucial role in choosing efficient appliances by indicating which products are energy-efficient and can help save money on utility bills.
