MIRAMAR, Fla. -- Bestselling financial author David Bach's latest book, "Go Green, Live Rich" talks about how people can save the environment and save big bucks.

"You can go green and now, today, you save money," Bach said. "You don't have to be rich. You don't have to be famous to care about the environment."

The book's headline says: "I think the average family can save somewhere between $3,000 to $5,000 this year by going green."

How can a family save that much money over the course of a year, NBC 6's Patricia Andreu asked.

"What I want you to do is find your litter factor," Bach said. "What are you spending money on every day that you could cut out right now and have less impact on the planet? Water's a great example. You could cut out $500 a year like that, just by cutting out bottled water. You've heard about brown bagging your lunch. I want you to green bag your lunch."

Bach said you can save at least $60 per year on plastic bags alone by using reusable containers.

"If you make your lunch and you stop going out every day and eating lunch out, we know for a fact you can save between $1,000 and $2,000 a year," he said.

On the home front, you can save big by buying nontoxic cleaners.

"More companies are making the products, and that's bringing the price down," Bach said. "If you want to save an absolute fortune, use a simple formula of baking soda, vinegar, boiling water, and you can save $580 a year on the bulk of your cleaning supplies."

Forget about rising gas prices. Mowing your lawn with an electric lawnmower will cost you about $5 per season.

Bach's book also explains how to take the money savings and make even more with eco-friendly investments.

"Start by investing in exchange traded mutual funds Â… that are now in the different sectors: water, energy," he said. "My prediction is you will see in the next 36 months a proliferation, if you will, of green investment products."
