PV solar is not economoincal in any part of the US except the South west, when you put all the cost together. Get Uncle Sam out of the Buisness of subisdizing an activity that does not make economic sense. We do not import any energy source that is converted into electirc power so this does not help our balance of payments or energy security.
Let the market regulate more economical cars, etc. Don't mess with the market to decide whether battery or hydrogen fuel cells are the next power source. I'd rather see hydrogen myself (no battery NiCd mining issues, replacement, etc.)
Donated leave to help a federal employee should be consider the same as a donation to an approved charity. If an employee itemizes their tax return, then the value of the donated leave should be included in the list of deductions. If an employee with an hourly rate of $50/hr donates 10 hours then $500 is considered a charitiable donation and can be added to the list of deductions.
