Can the usage of LEDs help reduce electricity bills?

I have the bug! 

Can you pull your own permits for electrical, plumbing, heating and cooling if you are going to live in the house in Harris County and for the city of Houston?

Okay, numbers:Purchase Price: $47,200 cash (County Foreclosure Auction)Renovations/Holding Costs: $33,792 cashSale Price: $129,900Closing Costs: $14,378Total Profit: $34,630Renovations (Contracted):New RoofNew Windows2 New Electric Subpanels for A/CRenovations (DIY):Gutted the kitchen, opened up wall into Bedroom #1Relocated front doorFramed out closet in what was the living room to make it Master BedroomAdded a half bath to the laundry room area which became master en-suite (the home was permitted as a 1.5 bathrooms and when we got there there was only 1 bathroom so we added the half bath)Redid the kitchen entirelyCompletely redid the bathrooms, turning one into a 4-pieceNew floors throughout houseNew landscapingI estimated about $30k in repairs (after initial walk-through and having already purchased the property).

Is gas/electric direct billed? 

(I have some extremely high quality electrical in one of my houses though...!)

All new windows, plumbing, electrical, roof, water heater, etc.I have to respectfully disagree on this.

I just bought a house in Laurel, MD with a brand new, never used white electric range.
