But they are not pessimistic about the sector. “The good news is that renewable energy has – at least on a levelized cost of electricity, or LCOE, basis – clearly achieved the long-awaited goal of grid competitiveness,” they say. Both onshore wind and solar projects have won auctions, in Morocco and Chile respectively, with bids of $30/MWh or less in the last 12 months. “These must be the lowest electricity prices, for any new project, of any technology, anywhere in the world, ever. And we are still going to see further falls in equipment prices,” they assert.
Electric bills for customers in the Houston area can more than double in summer months, mainly because air conditioning. Not coincidentally, electric rates also rise in the summer months because of this increase in demand. The most dramatic rate increases occur in month-to-month plans, but electric rates do increase across the board for all fixed-rate contract lengths.
Cavity wall insulation. Most homes built since 1920 have a gap between internal and external walls. Filling the cavity with insulating mineral wool and foam means cold air's kept out, and warm air stays in. It can save an average three-bedroom home up to £150/year. We've heard of certain cases where damp has formed after having cavity wall insulation installed, so make sure it's appropriate for your home.
Fixed-rate, long-term (contract) plans provide stability in electricity rates. If market energy costs suddenly trend upward where you live, you can rest assured that you won’t have to pay more out of pocket. However, if you want to switch to a different, lower-cost plan before the end of the contract term, you’ll likely have to pay a cancellation or early termination fee.
