In terms of renewable sources like solar and wind, weather impacts supply. California’s duck curve[cite] shows the difference between electricity demand and the amount of solar energy available throughout the day. On a sunny day, solar power floods the electricity generation market and then drops during sunless evening, when electricity demand peaks.[117]

Anyone on a standard rate tariff is at risk of seeing rising energy bills – so one of the best ways to protect from energy price increases is to switch to a fixed rate tariff. This means that for the duration of the deal, the cost of your energy and gas will be fixed. You may be able to switch to a cheaper fixed price tariff at any point, or you may have to pay a fee if you switch before the end of the deal – so check your paperwork.
You can organize and shop by pricing at YOUR individual usage level, which allows you to shop and compare energy plans based on the rates you’ll actually see appear on your bill, inclusive of taxes and hidden fees. You won’t be misled by the “teaser rates” tied with higher usage levels that many homes never experience, as their usage level never reaches that pricing tier.
