Henrico County in Virginia is asking its schools to conserve electricity due to a 25% increase in electricity rates, which is expected to cost the county an additional $5 million next fiscal year. The county is home to 37 data centers, with plans to build 17 more, which has led to concerns about the strain on the local power grid. The county manager has sent an email to employees asking them to take measures to reduce energy consumption, such as turning off lights and computers when not in use. The email notes that the rate increase is expected to be the first of many, with more increases anticipated in the future.
