Suppose that a report shows that, for a given year, the levelized cost of energy (LCOE) of new construction projects is expected to be $0.0545 per kWh for solar energy and $0.0995 per kWh for geothermal energy. Which form of energy has a better LCOE?(1 point)
Responses
geothermal energy, because the LCOE implies higher total production
geothermal energy, because the LCOE implies higher total production
solar energy, because the LCOE implies lower capital and operating costs
solar energy, because the LCOE implies lower capital and operating costs
solar energy, because the dollar amount per kWh is lower
solar energy, because the dollar amount per kWh is lower
geothermal energy, because the dollar amount per kWh is higher
