House Democrats plan to make at least part of Wednesday’s debate on a $789 billion spending bill for fiscal 2018 about restoring renewable energy funding at the Department of Energy through a slew of amendments that likely will slow down a final vote on the overall spending package.

Democrats are offering at least nine amendments in a bid to raise spending levels for the Energy Department’s Office of Energy and Renewable Energy, as well as individual programs to support electric vehicles and alternative fuels.
