Many communities search for new ways to provide energy for their citizens

Which energy-generating technologies are described in the chart? Add a label for each.

Energy-Generating Technology

Cost Analysis
Start up costs moderately high, operating costs low
Start-up costs moderate; overall operating and fuel costs comparatively low
Start-up cost low, fuel/operating costs comparatively low
High start-up costs; zero fuel cost
Moderately high start-up costs; zero fuel cost; needs a back-up system
Very high start-up costs, minimal fuel cost

Environmental Impact

Renewable energy source, requires open space

Fuel nonrenewable; contributes to greenhouse gas levels

Fuel nonrenewable; efficient use of fuel reduces greenhouse impact

Renewable, no effect on greenhouse gases; may disrupt lithosphere

Renewable energy source, no greenhouse gases; noisy; impacts bird populations

Renewable energy source, alters land use and natural habitats

Wind

Geothermal

Hydroelectric

Coal

Natural gas

Solar

Based on the provided cost analysis and environmental impact descriptions, the energy-generating technologies can be labeled as follows:

  1. Wind

    • Cost Analysis: Start-up costs low, fuel/operating costs comparatively low
    • Environmental Impact: Renewable energy source, no greenhouse gases; noisy; impacts bird populations

  2. Geothermal

    • Cost Analysis: High start-up costs; zero fuel cost
    • Environmental Impact: Renewable, no effect on greenhouse gases; may disrupt lithosphere

  3. Hydroelectric

    • Cost Analysis: Start-up costs moderately high, operating costs low
    • Environmental Impact: Renewable energy source, alters land use and natural habitats

  4. Coal

    • Cost Analysis: Start-up costs moderate; overall operating and fuel costs comparatively low
    • Environmental Impact: Fuel nonrenewable; contributes to greenhouse gas levels

  5. Natural Gas

    • Cost Analysis: Very high start-up costs, minimal fuel cost
    • Environmental Impact: Fuel nonrenewable; efficient use of fuel reduces greenhouse impact

  6. Solar

    • Cost Analysis: Moderately high start-up costs; zero fuel cost; needs a back-up system
    • Environmental Impact: Renewable energy source, requires open space

These labels categorize each technology based on its cost characteristics and environmental impact.
