Wind turbines use energy from the wind to provide mechanical and electrical power.
In MegaWatt, the wind technology card is a low cost and low environmental impact option. Its weakness is a low power capacity due to variable wind and high land use.
Solar panels are made from photovoltaic cells, which harness the Sun’s energy and convert it to electrical energy.
In MegaWatt, the solar technology card is a low cost and low environmental impact option. Its weakness is a low power density due to the large amount of area required, and that it can only produce electricity during the day.
Nuclear power uses the energy released when a uranium atom splits through a process called nuclear fission.
In MegaWatt, nuclear is a low environmental impact card with a high power capacity and high cost.
Hydropower uses the flow of water to generate electricity. This flow of water is often created by building a dam to block a valley or river.
In MegaWatt hydropower has a high capacity with a moderate cost and environmental impact.
Biomass energy involves growing plants not for eating, but to be burned to produce heat.
In MegaWatt, biomass is a high cost, fairly low environmental impact card. Combine this with the carbon capture and storage upgrade to reduce your grid's environmental impact even further.
The coal used in power stations is a fossil fuel formed over millions of years from the remains of decaying plants, which became peat and was then fossilised.
In MegaWatt, coal is a low cost and high capacity technology, but an option with a high environmental impact.
Gas is a fossil fuel formed over millions of years from the remains of marine microorganisms, which broke down into hydrocarbons (i.e. natural gas) as they were mixed with sediment and buried.
In MegaWatt, gas is a low cost option with moderate environmental impact.
