Exploring Green Technology

What are the main sources of renewable energy in the energy sector?

• Tidal, fossil fuels, oil

• Nuclear, coal, natural gas

• Hydrogen, propane, charcoal

• Solar, wind, hydroelectric, biomass, and geothermal energy.

How does solar energy contribute to reducing carbon emissions?

• Solar energy reduces carbon emissions by providing a clean, renewable source of electricity that replaces fossil fuels.

• Solar energy is a non-renewable resource.

• Solar energy has no impact on carbon emissions.

• Solar energy increases reliance on fossil fuels.

What are the benefits of electric vehicles in the transportation sector?

• Electric vehicles reduce emissions, lower operating costs, improve air quality, and decrease fossil fuel dependence.

• Electric vehicles are more expensive to maintain

• Electric vehicles increase fuel consumption

• Electric vehicles produce more noise pollution

Explain the role of public transportation in promoting sustainable urban development.

• Public transportation has no impact on urban land use planning.

• Public transportation is primarily used for long-distance travel.

• Public transportation increases traffic congestion in urban areas.

• Public transportation plays a crucial role in promoting sustainable urban development by reducing emissions, enhancing land use efficiency, and providing equitable access to mobility.

What technologies are used in wastewater management to ensure clean water?

• Reverse osmosis for drinking water only

• Incineration of wastewater

• Solar energy for water heating

• Technologies used in wastewater management include biological treatment, sedimentation, filtration, chemical disinfection, and membrane filtration.

How can recycling reduce the amount of waste in landfills?

• Recycling only benefits the economy and does not affect waste management.

• Recycling increases the amount of waste in landfills by creating more products.

• Recycling diverts waste from landfills by converting used materials into new products.

• Recycling has no impact on landfill waste and is purely for environmental awareness.

What practices in agriculture can enhance sustainability and reduce environmental impact?

• Deforestation for crop expansion

• Monoculture farming

• Excessive use of chemical fertilizers

• Practices such as crop rotation, organic farming, and conservation tillage enhance sustainability and reduce environmental impact.

Describe the importance of afforestation in combating climate change.

• Afforestation increases urban pollution levels.

• Afforestation is important in combating climate change as it absorbs carbon dioxide, enhances biodiversity, and improves soil health.

• Afforestation has no impact on wildlife habitats.

• Afforestation reduces the amount of rainfall in an area.

How does precision farming contribute to efficient resource use in agriculture?

• It leads to higher water consumption for irrigation.

• Precision farming contributes to efficient resource use by enabling targeted application of inputs, reducing waste, and optimizing crop management.

• It increases the use of chemical fertilizers indiscriminately.

• It promotes traditional farming methods without technology.

What are the challenges faced in implementing green technology in developing countries?

• Advanced infrastructure

• High levels of technical expertise

• Challenges include limited financial resources, lack of infrastructure, insufficient technical expertise, regulatory barriers, and cultural resistance.

• Abundant financial resources
