How can I reduce electricity bills from air conditioning?

A small change can yield big results. Reducing thermostat levels by 2 degrees Fahrenheit can cut reduce electricity bills by 10 percent.

What are the benefits of a distributed electrical system?

<span data-sheets-value="{"1":2,"2":"A distributed electrical system is a more flexible system, with lower investments in transmission infrastructure, reduced energy losses and reduced need to build high-cost power plants. It features smaller, more localized power providers.

Why is it hard to integrate wind and solar into electricity grids?

<span data-sheets-value="{"1":2,"2":"Power grid operators and utilities need to balance supply and demand in real-time. Too much or too little electricity can result in unforeseen voltage fluctuations and service disruptions. On the other hand, renewable sources may also be underutilized. For example, it may be windier at night, when demand is lowest."}" data-sheets-userformat="{"2":4225,"3":{"1":0},"10":2,"15":"Arial"}">Power grid operators and utilities need to balance supply and demand in real-time.
