Renewable energy sources are best described as

• those that are the most cost-effective and support the largest job market

• those that are, or can be, perpetually available

• those that are dependent on increasing public demand and decreasing supply

• those that are being depleted at a faster rate than they are being replenished

• those that are reusable, and therefore eliminate waste energy released into the environment

An energy-efficient building might include all of the following except

• building materials with low thermal mass

• a green roof

• reused or recycled construction materials

• photovoltaic solar cells as a source of electricity

Which source of energy is NOT (ultimately) solar-based

• Wind

• Biomass

• Tides

• Coal

• Hydroelectricity

Which of the following demonstrate(s) the use of passive solar energy?

A study of small wind turbines in the Netherlands tested the energy output of several models. The results for two models are shown in the graphs below. Which statement can be inferred from the these data?

• As wind speed increases, energy output decreases

• The annual energy output of model 1 can exceed 6,000 kWh

• As energy output surpasses 50 kWh per week, noise pollution increases

• Model 2 is likely to cause more bird and bat deaths

• Model 1 is more cost-effective

The primary sources of renewable energy in the US are

• Solar and wind energy

• hydroelectricity and tidal energy

• Biomass and hydroelectricity
