Cost of electricity by source - Wikipedia

In comparison, coal-fired plants are between US$65 and $150 per MWh, nuclear power at US$97 per MWh. Small photovoltaic power plants on roofs of houses are still at 184300 USD per MWh, but which can do without electricity transport costs. Onshore wind turbines are 3277 USD per MWh. One drawback is the intermittency of solar and wind power.
