Which energy source releases the most climate-altering carbon pollution?
a) Oil
b) Coal
c) Natural Gas
d) Solar
b) Coal
Coal is especially damaging to our planet, releasing 70% more carbon pollution than natural gas for every unit of energy produced. In contrast, rooftop solar panels do not generate any pollution.

The power of wind has been harnessed throughout recorded history, but when was the world’s first megawatt-size wind turbine connected to the electric grid?
a) 1881
b) 1941
c) 1991

Of all new generating capacity added to the U.S. electrical grid in 2015, what percentage was solar?
a) 5.5%
b) 29.4%
c) 13.6%
d) 17.2%
b) 29.4%
While solar accounts for less than 2% of U.S. electrical generating capacity overall, it is one of the fastest-growing energy markets in the country. With solar power continuing to get more affordable and new installations happening every day, the solar industry is booming. For the first time, more solar generating capacity was added in 2015 than natural gas in the U.S. (Source: FERC)

EDP installed a solar plant, in a pioneering way at European level. What are the advantages of using surfaces already occupied by hydraulic plants to also install solar power plants?
A) It allows to use the solar energy to heat the water in the dams and to introduce it already hot in the conduit of surrounding dwellings.
B) The use of other areas of recognized utility is avoided, and the connection to the already installed electrical network is used, which the hydroelectric power stations only use seasonally.
C) Installing a solar power plant near a hydroelectric power plant will contribute to a greater condensation of water in the area and increase the level of rainfall, benefiting the localities suffering from extreme drought.
B) The use of other areas of recognized utility is avoided, and the connection to the already installed electrical network is used, which the hydroelectric power stations only use seasonally.
