Baseload power

Baseload power is a long term, continuous, and reliable power supply, often supplied by hydroelectricity, coal or nuclear power. It is a stumbling block for many forms of renewable energy.

Options include:

• Solar thermal electricity using molten salt which can store heat for many hours. Already on a semi-commercial basis in Spain
• Hydroelectricity. Unfortunately the dams have significant negative environmental impact, also affecting fish stocks.

Possibilities (still at the research stage) include:

• Wind power storing the energy as air pressure in underwater balloons. Still at the concept stage.^[1]
• More cost-effective batteries
