A coastal region uses tidal, solar, gas and geothermal energy resources. Which statement about how reliably these resources can supply energy is correct?
Tidal can give a continuous supply because the times of the tides can be forecast.
Geothermal can give a steady supply because hot rocks do not depend on the weather.
Gas cannot give a reliable supply because its reserves will eventually run out.
Solar can give a steady supply all year because sunlight reaches the cells every day.
