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.

To skirt the late summer electricity rate hikes, a little bit of planning can really pay off. Try to avoid signing new long-term electricity contracts in late summer. While it may be impossible to escape signing a new electricity contract if you’re moving during that time, just know that a short-term plan may make more sense until the rates go back down in the fall.  That way you’re not stuck paying a premium rate for an entire year or more.
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]

Electricity cannot be stored as easily as gas, it is produced at the exact moment of demand. All of the factors of supply and demand will therefore have an immediate impact on the price of electricity on the spot market. In addition to production costs, electricity prices are set by supply and demand.[120] However, some fundamental drivers are the most likely to be considered.
Because prices from energy companies in Maryland rise and fall depending on the wholesale price of energy, residents may want a more stable rate for a longer period. A fixed-rate energy plan offers you just that, with a consistent rate for the duration of your agreement at current energy prices – regardless of fluctuations in the energy market. This could mean protection from rate spikes and savings for electric utility customers.
When you’re choosing a new energy deal, think about whether to go for dual fuel (where you get both your gas and electricity from the same company) or separate tariffs (where you get gas from one company, and electricity from another). It’s worth checking both options, as the combined price of separate tariffs can sometimes be less than a dual fuel offer.
How does that work? Spark Energy buys electricity and competes in the market for the best price -- a competition that ultimately drives prices down and allows us to deliver more value for your money. In Texas, switching to a different electricity provider is kind of like changing to a different long distance company. When you switch to Spark Energy, the utility will continue to deliver electricity to your home but Spark Energy will handle all the billing, including the utility’s delivery fees and the electricity you actually use.

Technology that now allows smaller quantities of power to be generated closer to the end-users at prices not too much higher than grid-based power are undermining those economies of scale. More efficient turbines, for example, allow large power users like cement plants and petrochemical factories to come off the grid. Today the limiting factor for large companies to come off the grid often isn’t the efficiency of the power generation technology, but the lack of easy availability of fuel, such as gas or coal to power these turbines Even this problem is being solved by innovations like mini-liquefied natural gas projects.
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.
