What do developing countries mainly need energy for?
Developing countries mainly need energy for subsistence tasks such as cultivating, cooking, and heating homes.
The U.S. uses nearly of global energy, despite having only 5% of the world's population.
The U.S. uses nearly 20% of global energy, despite having only 5% of the world's population.
True or False?
Most developing regions use more energy than developed regions.
False.
Most developed regions use more energy than developing ones, because energy use is not evenly distributed between them.
Which sectors need the most energy in industrialized nations?
In industrialized nations, transportation and industry need more energy because they use more mechanized equipment and technology.
What are the main fuels for vehicles?
The main fuels for vehicles are oil and gasoline.
Which fuel remains the main fuel for electricity generation?
Coal remains the main fuel for electricity generation.
Natural gas is the secondary fuel for electricity generation and the main fuel for .
Natural gas is the secondary fuel for electricity generation and the main fuel for heating.
What percentage of the world's energy came from fossil fuels in 2022?
In 2022, 80% of the world's energy came from fossil fuels, while renewable energy made up 12.7%.
Which subsistence fuel do many people in developing countries rely on?
Many people in developing countries rely on biomass, such as fuelwood, because it can be easily obtained.
True or False?
Relying on fuelwood for energy has little environmental impact.
False.
Collecting fuelwood can drive deforestation.
How does a country's reliance on fossil fuels change as it develops?
A country's reliance on fossil fuels increases as it develops, because it uses more energy for industry, transportation, and technology and rising incomes increase demand for consumer goods.
How does global population growth affect energy demand?
As the global population increases, energy demand increases, because more people need energy for electricity, transport, heating, and cooling.
Why does a higher demand for food increase energy demand?
A higher demand for food leads to more intensive farming, which needs energy for machines, light, and heat.
How does increasing urbanization raise energy demand?
Increasing urbanization raises energy demand through more domestic appliances, heating, and lighting.
Define economic viability of an energy source.
An energy source is economically viable when the cost of extracting and developing it is less than the money it will make.
True or False?
U.S. regions that import their fuel tend to have the cheapest electricity.
False.
Regions that import fuel have the most expensive electricity, such as Hawaii, which relies on imported petroleum; the cheapest rates are in regions with abundant local fuel sources.
Which physical factor affects whether coal, oil, and gas are available?
Geology affects whether coal, oil, and gas are available.
Hydraulic fracturing, or fracking, is a new technology used to extract gas.
Hydraulic fracturing, or fracking, is a new technology used to extract shale gas.
How do governments encourage the use of renewable energy sources?
Governments encourage renewable energy by providing incentives such as tax rebates or subsidies, and may raise taxes to discourage fossil fuel power stations.
