Landfill gas, solid waste energy
Pros: Efficient use of waste, reduces methane emissions.
Cons: Large areas of landfill are required, compared to plants
powered by fossil fuel. Pollution. Recycling reduces
landfills.
Wind turbines
Pros: No pollution, limited maintenance, relatively inexpensive to
build.
Cons: No energy when the wind isn't blowing. The towers are
visually displeasing to some people. It creates noise, and can
be harmful to birds and wildlife. It also requires a lot of
land.
Biomass power
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.
Hydroelectric power
Pros: It's clean; abundant, where there are bodies of water. Cost
competitive energy source. Recreational opportunities.
Cons: Dams can create environmental concerns, and it is restricted
to where there is water. High upfront capital costs.
Solar power
Pros: Unlimited supply of sunlight and no pollution. Since you will
be meeting some of your energy needs with the electricity
our solar system has generated, your energy bills will drop.
Cons: It relies on sunlight, so it doesn't generate electricity at night
or when overcast. It's more expensive than other sources. It
takes a large geographical footprint to generate a significant
amount of energy. Panels can cause glare.Transportation and
installation of solar systems have been associated with the
emission of greenhouse gases.
After looking at the pros and cons, my opinion is the same. We should use this when and where it makes sense. Like it wouldn't work to put all solar power in Alaska. It’s going to take a long time and billions of dollars to convert everything over. We have enough fossil fuels to last us a long time. So save where it make sense.
