Save Money Now,do a miny energy audit.

One of the first things you should do and one of the easiest is to go around your house or place of business and do a mini energy audit and see can you change your old incandescent bulbs with new energy saving CFL bulbs (CFL=compact fluorescent light) they will last at least for up to 5 times longer than normal bulbs and use much less power.
In some instances you could use led bulbs which are bulb shaped fittings covered with leds (LED=light emitting diode) which last even longer than CFLs and use a tiny amount of power to run.
The initial cost of buying all new bulbs for your house may seem a little steep and if you cant manage it at once try buying one or two at a time and replacing the old bulbs when they blow, this way the cost would be spread out over time but you will eventually end up with all your bulbs replaced.
