All Flashcards
Define 'total energy consumption'.
The total amount of energy used by a country or entity.
What is 'biomass'?
Organic matter used as a fuel, especially in developing nations.
Define 'commercial energy'.
Energy sources bought and sold, like natural gas and coal.
What are 'fossil fuels'?
Non-renewable energy sources formed from ancient organic matter.
Define 'hydropower'.
Electricity generated from the power of moving water.
What is 'nuclear power'?
Electricity generated from nuclear fission reactions.
Define 'biofuels'.
Fuels derived from recently living organic matter.
What is 'per capita energy consumption'?
The average energy consumed per person in a given area.
Define 'carbon footprint'.
The total greenhouse gas emissions caused by an individual or organization.
What is 'renewable energy'?
Energy from sources that are naturally replenished.
How does economic development influence energy consumption?
Industrialization leads to higher energy demand, increasing overall consumption.
Explain the relationship between population growth and energy use.
More people require more resources and energy, leading to increased energy consumption.
What is the role of technological advancements in energy consumption?
Technology can increase or decrease energy use depending on its efficiency and application.
Why are fossil fuels the leading source of electricity globally?
Due to their affordability, accessibility, and established infrastructure.
Why is natural gas increasing in popularity?
Due to its relative abundance and affordability compared to other fossil fuels.
Why is biomass commonly used in developing nations?
It is easily accessible and low in cost, making it a practical energy source.
Why is transitioning to renewable energy crucial for sustainability?
To reduce reliance on fossil fuels, mitigate climate change, and ensure long-term energy security.
How does energy use correlate with development?
Higher energy use often correlates with higher development but can also lead to higher environmental impact.
How does energy consumption differ between developed and developing countries?
Developed nations have higher per capita energy consumption and rely more on commercial energy sources compared to developing nations.
What are the main uses of energy in the residential sector?
Water heating, space heating, and cooling.
What is the effect of burning biomass indoors?
Indoor air pollution, respiratory problems, and deforestation.
What are the environmental consequences of fossil fuel combustion?
Greenhouse gas emissions, climate change, air pollution, and acid rain.
What are the potential impacts of damming rivers for hydropower?
Habitat destruction, altered river flow, and displacement of communities.
What is the effect of increased energy consumption in the transportation sector?
Increased greenhouse gas emissions and air pollution, especially from petroleum use.
What is the effect of increased industrial energy consumption?
Increased air and water pollution, resource depletion, and greenhouse gas emissions.
What are the environmental consequences of nuclear power generation?
Risk of nuclear accidents and the challenge of long-term radioactive waste disposal.
What is the impact of deforestation for biomass fuel?
Habitat loss, soil erosion, and reduced carbon sequestration.
What is the effect of using biofuels?
Reduced dependence on fossil fuels, but potential impacts include land use changes and competition with food crops.
What are the effects of increased carbon footprint?
Climate change, global warming, sea level rise, and extreme weather events.
What are the consequences of unsustainable energy consumption?
Environmental degradation, resource depletion, and climate change.
