DERs: Harnessing Distributed Energy Resources

DERs—distributed energy⁣ resources—are​ transforming⁣ the way energy is⁣ generated‌ and consumed. From homes to ⁤businesses⁣ to entire communities, DERs are becoming ‌more ‌and more ubiquitous. In this​ article, we’ll explore‌ the⁤ role of DERs in​ energy production, and how the renewable, distributed energy future is‌ unfolding before our very eyes.

1. What Are Distributed ⁤Energy Resources?

Distributed energy ⁤resources (DERs) are energy resources‍ located and operated ‍near ​the⁢ consumer or‌ user, such as home‍ solar systems, rooftop wind energy ⁢systems, and distributed-scale batteries. They have ‌often been referred to as‌ ‘behind-the-meter’ as the⁤ energy is ‌generated and stored in locations behind the traditional electricity⁣ meter.

DERs provide substantial advantages for consumers, businesses and ‌the electrical ​grid.​ They offer:

  • Reduced electricity​ costs – ⁢DERs reduce the need for ​customers to purchase electricity from the grid, leading⁣ to⁤ overall lower electricity bills for⁣ consumers.
  • More reliable electricity ⁢– DERs enable customers to produce ⁤electricity on-site, reducing the possibility of an outage due to grid​ failure.
  • Emissions-free electricity – By using renewable energy ‍sources, such as‍ solar​ and wind, ⁤DERs ⁢can ‍reduce our reliance on fossil-fuel⁤ energy production and ​help tackle ⁣the climate change crisis.

There is a ​growing interest in DERs, driven by the increased ⁢recognition of ⁢their benefits, the development‌ of ‌renewable energy sources, and the emergence⁣ of ​various technologies such as the internet​ of things (IoT) and ⁣cloud ‍computing.
