I work 100% remotely. Can I claim my internet and electricity at all??

If you are a W-2 employee, none of your employee business expenses are deductible on a federal tax refund due to the tax code changes in effect for tax years 2018 thru 2025

No, for federal if you are an employee.  If you are an employee, you cannot claim your internet or electricity at all.  Employee job related expenses are not tax deductible on your federal return. 

Depending on which state you live in, you may be able to claim a deduction for your job related expenses.  Which state are you in?

If you are self-employed, receiving a 1099-NEC instead of a W-2, then yes, you could take a prorated deduction on your Schedule C.
