Environmentally friendly compared to gas or oil furnaces (no combustion).
Not a significant source of pollution.
High upfront costs with implementing geothermal energy. ($10,000-$20,000)
More suitable for new home builds as retrofitting involves large scale excavation.
Solar energy is a renewable energy source. This means that we cannot run out of solar energy, as opposed to non-renewable energy sources
The potential of solar energy is beyond imagination. The surface of the earth receives 120,000 terawatts of solar radiation (sunlight) – 20,000 times more power than what is needed to supply the entire world
In 2010, coal received $1,189 billion in federal subsidies and support for electricity production while solar is not far behind at $968 billion.[
Solar energy is an intermittent energy source. Access to sunlight is limited at certain times (e.g. morning and night). Predicting overcast days can be difficult. This is why solar power is not our first choice when it comes to meeting the base load energy demand. However, solar power has fewer problems than wind power when it comes to intermit
Clean Source of Power
Threat to Wildlife
Dependency on Fossil Fuels is Reduced
Not Totally Clean When Burned
Can Lead to Deforestation
Abundant supply, concentrated in industrialized countries
Coal is nonrenewable. There is a finite supply.
Coal contains the most CO2 per BTU, the largest contributor to global warming.
Easily Accessible and Economical
Substantial Type of Energy
Not a Renewable Source of Energy
Natural gas is abundant and a major source of energy.
A relatively clean fossil fuel, a ‘bridge’ fuel
Natural gas is itself a powerful greenhouse gas.
Natural gas a nonrenewable resource
Low Operating Costs
Radioactive Waste Disposal
