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]

In Maryland, you have the power to choose your electricity and natural gas suppliers. More than 500,000 Marylanders have already switched energy suppliers. Need a good reason to switch? Some suppliers regularly offer rates and service that are 10% or more cheaper than the utility. Things could get worse - Baltimore Gas and Electric Co. has proposed a rate increase it says would boost the average residential customer's total bill by $5.77 per month. A recent Choose Energy survey found that more than 86 percent say they've never chosen a competitive Maryland electricity plan, meaning they're probably paying more than they have to for energy. Don't pay more. Just enter your ZIP code above to see how you can begin saving with Choose Energy!
It’s very important to do your own research to understand the business focus of the company you are considering, as well as tax advantages (and possible disadvantages) if the company is a limited partnership. For example, Seadrill Ltd. SDRL, -1.72%  provides offshore-drilling services worldwide. Seadrill Partners LLC SDLP, -3.22%  operates offshore-drilling rigs under specific contracts with several major oil companies, including Exxon Mobil Corp. XOM, +0.17%  and Chevron Corp. CVX, -0.43%  
The local electric company is the utility – that’s the company who owns the infrastructure, including the poles and power lines that deliver electricity to your home. They are who you call if your power goes out or there's an emergency. But in almost every city in Texas, you must choose another company to supply that energy, called a Retail Electric Provider (REP). These REPs, like Spark Energy, allow you to choose electricity plans that offer competitive prices and plans to meet your needs.
In Texas' deregulated energy market, customers must pick their own electricity provider, all of which offer different rates per hour of power usage. You can shop for other power plans on the state-run website,  www.powertochoose.org, or try an alternative website, like www.texaspowerguide.com to help find the cheapest plan. Keep in mind that many retail electricity contracts carry penalties for early termination.
There’s some smart money placing big bets on a rebound for oil. Blackstone Group LP BX, +0.75%  President Hamilton “Tony” James said last month that the company was “scrambling” to invest up to $10 billion in energy companies, according to Bloomberg. Blackstone CEO Stephen Schwarzman said during the company’s earnings call on Jan. 29 that the majority of Blackstone’s energy investments were “oil-price agnostic, including energy-transportation infrastructure where we have off-take agreements, merchant power, renewables and other types of energy-oriented investing.”

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.
