Distributed energy generation (DEG) is a term used to describe the shift from centralized energy generation, such as power companies, to a source — typically a renewable energy source — closer to the user.
It is most often seen in the form of solar panels on the rooftops of houses or office buildings, but DEG also includes wind turbines installed on farms, micro-hydro generators on properties with streams or rivers running through them, and natural gas turbines. DEG has gained significant traction over the past two decades because it allows residents and businesses to generate their own electricity and offset some of their expenses. Due to the increased use of DEG, Trend Micro decided to investigate DEG device security focusing on solar devices because of their popularity.
