Fossil fuels—coal, oil, and natural gas—do substantially more harm than renewable energy sources by most measures, including air and water pollution, damage to public health, wildlife and habitat loss, water use, land use, and global warming emissions.
Explanation: Loss of animal species, land degradation, and lower availability of freshwater are possible cost of using 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.
How does the use of nonrenewable resources compare to the use of renewable resources? a. The use of renewable resources is potentially more harmful to the environment than the use of nonrenewable resources. The use of renewable resources is more common and widespread than the use of nonrenewable 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.
How these types of renewable energy work
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 |
Renewable energy sources are not able to supply baseload power generation – meaning they cannot supply a region’s continuous energy demand. Electric power generation must come from other sources, like natural gas – an abundant and clean source of energy.
100% renewable energy and net-zero greenhouse gas definitions are political in nature and vary by place and time. However, recent studies show that a global transition to 100% renewable energy across all sectors – power, heat, transport and desalination well before 2050 is feasible.
1. Renewable systems are reliable, even at night and on windless days: One of the most common fallacies about renewable energy is that it cannot be relied upon to satisfy our electricity demand given that the sun does not always shine and the wind does not always blow.
Disadvantages of Renewable Energy
What are the disadvantages of renewable energy?
Pros: It is abundant, and can be used without interruption, cleaner than fossil fuel. Cons: Can result in air pollution, takes a lot of energy to produce, can be seasonable and competes with food production. Landfill gas, solid waste energy comes from harnessing the decomposition of organic material.
Various Disadvantages of Wind Energy
On the pros side, wind is a clean, renewable energy source, and is one of the most cost-effective sources for electricity….Pros and cons of wind energy.
Pros of wind energy | Cons of wind energy |
---|---|
Renewable & clean source of energy | Intermittent |
Low operating costs | Noise and visual pollution |
Efficient use of land space | Some adverse environmental impact |
Advantages of Wind Power
Why do the turbines not spin at times? The most common reason that turbines stop spinning is because the wind is not blowing fast enough. Most wind turbines need a sustained wind speed of 9 MPH or higher to operate. Technicians will also stop turbines to perform routine maintenance or repairs.
Wind lease terms vary quite a bit, but general rules of thumb are: $4,000 to $8,000 per turbine, $3,000 to $4,000 per megawatt of capacity, or 2-4% of gross revenues. Larger turbines should translate to larger payments.
