1. If possible try Solar Cooker as much as possible. This can help you is recovering cost within 6-7 months and then help you in savings.
2. Get your car fitted with CNG/ LPG. If you are a daily user then you can expect the cost to be recovered with an years time.
3. use CFL in cutting your electricity bills (but practically speaking it help you in overcoming voltage fluctuation, and is as instant as a bulb. I am not convinced with cost/saving ratio.)
