*Save Over £390 - Over 10% of the estimated quotations raised by users of the Simply Switch Website to switch their gas and electricity suppliers between 01/02/2015 - 01/06/2015 produced a predicted annual saving of £390 or more. Current combined spend for gas and electricity of between £84 and £6869. Savings may have included Direct Debit and online discounts. Energy prices vary by usage and postcode.
Technology also provides a long-term answer, even if it contributes to the problem in the short-term, as described earlier. As renewable power and storage technologies become cheaper and more efficient they will gradually allow for the implementation of cheaper mini-grids and smart grids, increasingly within the reach of the really poor, even in urban areas. Perhaps, grids will one day become marketplaces allowing people to sell excess power from their solar installations to those who have a need for power at that time. Prices can be set dynamically to allow supply to match demand.
You betcha! Most Texas electricity suppliers offer plans that include a percentage of energy sourced from renewable resources, such as hydro power, wind power and solar power. Some are totally sourced that way. These plans are a great way for Texas energy customers to help the environment without breaking the bank. In addition to green energy plans, many Texas suppliers give customers the option to purchase renewable energy certificates, or RECs, that further offset customers’ carbon emissions. The purchase of RECs also helps fund research and usage of renewable energy sources, so that Texas can stay at the forefront of eco-friendly power technology.
In Dallas, 0% of people have switched to a plan that has some renewable energy component to it. Another 0% have switched to a plan that is partially renewable, while 0% have switched to a plan that powers homes completely by renewable electricity. This of course means that 100% of people have remained on a plan powered by traditional sources of electricity such as coal or nuclear power.
Wind and solar power are non-dispatchable. Such power is normally sold before any other bids, at a pre-determined rate for each supplier. Any excess is sold to another grid operator, or stored, using pumped-storage hydroelectricity, or in the worst case, curtailed. Curtailment could potentially significantly impact solar power’s economic and environmental benefits at greater PV penetration levels. Allocation is done by bidding.
Most common distribution network and generation is done with 3 phase structures, with special attention paid to the phase balancing and resulting reduction of ground current. It is true for industrial or commercial networks where most power is used in 3 phase machines, but light commercial and residential users do not have real-time phase balancing capabilities. Often this issue leads to unexpected equipment behavior or malfunctions and in extreme cases fires. For example, sensitive professional analogue or digital recording equipment must be connected to well-balanced and grounded power networks. To determine and mitigate the cost of the unbalanced electricity network, electric companies in most cases charge by demand or as a separate category for heavy unbalanced loads. A few simple techniques are available for balancing that require fast computing and real-time modeling.
The UK has been a net importer of energy for over a decade, and as their generation capacity and reserves decrease the level of importing is reaching an all-time high. Their fuel price's dependence on international markets has a huge effect on the cost of electricity, especially if the exchange rate falls. Being energy dependent makes their electricity prices vulnerable to world events, as well.
