Identify the advantages and disadvantages of renewable and nonrenewable energy resources.
1. less expensive than alternatives
2. can be replaced in a short period of time
3. some resources cannot be used in all regions
4. hydroelectric dams can damage ecosystems
5. are in limited supply
6. do not produce carbon dioxide
produce carbon dioxide when burned
Renewable Energy Resources:
Advantages:
1. Less expensive than alternatives: Renewable energy resources, such as solar and wind power, can be cheaper in the long run compared to nonrenewable resources, as there is no need for constant fuel purchases.
2. Can be replaced in a short period of time: Renewable energy resources are constantly replenished and can be harnessed continuously, making them a reliable source of energy.
3. Do not produce carbon dioxide: Renewable energy resources do not emit greenhouse gases during energy production, which helps in reducing air pollution and combating climate change.
Disadvantages:
1. Some resources cannot be used in all regions: Certain renewable energy resources, such as solar and wind power, may not be suitable for all geographical locations, limiting their availability.
2. Hydroelectric dams can damage ecosystems: Building large-scale hydroelectric dams can have negative impacts on local ecosystems and disrupt natural habitats for wildlife.
Nonrenewable Energy Resources:
Advantages:
1. Readily available: Nonrenewable energy resources, such as fossil fuels, are currently abundant and widely available in many parts of the world.
2. Can produce large amounts of energy: Nonrenewable energy resources have high energy density, allowing them to generate large amounts of power relatively quickly.
Disadvantages:
1. Are in limited supply: Nonrenewable energy resources are finite and will eventually be depleted, leading to potential energy shortages in the future.
2. Produce carbon dioxide when burned: Burning fossil fuels releases carbon dioxide and other greenhouse gases into the atmosphere, contributing to climate change and air pollution.
