Question: How can a global dependence on fossil fuels have associated social costs?

How might a dependence on fossil fuels?

The United States gets 81% of its total energy from oil , coal , and natural gas, all of which are fossil fuels . We depend on those fuels to heat our homes, run our vehicles, power industry and manufacturing, and provide us with electricity.

How a global dependence on fossil fuels can lead to international security risks?

a. Explain how a global dependence on fossil fuels can lead to international security risks . As demand increases, the costs of fossil fuels increases. This increased demand coupled with the diminishing supply will lead to increased competition over the limited resources.

Which of the following is a possible cost of using renewable resources a loss of animal species?

Explanation: Loss of animal species , land degradation, and lower availability of freshwater are possible cost of using renewable resources . Renewable resources are resources that can be replaced naturally and used repeatedly. Loss of animal species means disappearance , dying or extinction animals .

Why might it be advantages to use nonrenewable resources over renewable resources?

Why might it be advantageous to use nonrenewable resources over renewable resources ? a. The use of nonrenewable resources can be cheaper and more efficient than the use of renewable resources . Using alternative energy technology increases the demand for fossil fuels.

What are the negatives of fossil fuels?

Global warming pollution When we burn oil, coal, and gas, we don’t just meet our energy needs—we drive the current global warming crisis as well. Fossil fuels produce large quantities of carbon dioxide when burned. Carbon emissions trap heat in the atmosphere and lead to climate change.

What are the disadvantages of fossil fuels?

Fossil fuels have been used for centuries to generate power, but there are many disadvantages associated with their use: Fossil fuels pollute the environment. Fossil fuels are non-renewable and unsustainable. Drilling for fossil fuels is a dangerous process.

What two countries have nearly 50% global coal reserves?

Coal is the most widely used source of energy with the United States and Russia being the two countries that have nearly 50% of the global coal reserves.

What effect does burning fossil fuels have on the atmosphere?

When fossil fuels are burned , they release nitrogen oxides into the atmosphere , which contribute to the formation of smog and acid rain. The most common nitrogen-related compounds emitted into the air by human activities are collectively referred to as nitrogen oxides.

Which contrasts best hydropower and geothermal energy?

Answer. Geothermal energy is produced from steam. Hydroelectric energy is produced from running water as a result of water cycle.

Which of the following is an example of a renewable resource?

Renewable resources include solar energy , wind , falling water, the heat of the earth (geothermal), plant materials ( biomass ), waves, ocean currents, temperature differences in the oceans and the energy of the tides.

Which of the following would not be considered a renewable resources?

Earth minerals and metal ores, fossil fuels (coal, petroleum, natural gas) and groundwater in certain aquifers are all considered non- renewable resources , though individual elements are always conserved (except in nuclear reactions).

What is a possible cost of using renewable energy resources?

Hydroelectric power is the cheapest source of renewable energy , at an average of $0.05 per kilowatt hour (kWh), but the average cost of developing new power plants based on onshore wind, solar photovoltaic (PV), biomass or geothermal energy is now usually below $0.10/kWh.

What are the advantages and disadvantages of renewable resources?

Disadvantages of renewable energy resources

Energy Resource Advantages Disadvantages
Hydroelectric power stations Clean and cheap to run Expensive to set up and output could be affected by drought
Solar cells Clean and cheap to run Not always sunny and output does not always outweigh initial cost to set up

What are the advantages of renewable resources?

Benefits of Renewable Energy Generating energy that produces no greenhouse gas emissions from fossil fuels and reduces some types of air pollution. Diversifying energy supply and reducing dependence on imported fuels. Creating economic development and jobs in manufacturing, installation, and more.

What is the difference between renewable and nonrenewable resources?

Nonrenewable energy resources , like coal, nuclear, oil, and natural gas, are available in limited supplies. Renewable resources are replenished naturally and over relatively short periods of time. The five major renewable energy resources are solar, wind, water (hydro), biomass, and geothermal.
