With a gallon of gas now hanging around $4 a gallon in many areas on the country, people have been looking for alternatives to gas-guzzling SUVs.

According to Motor Trend magazine, sales of the Toyota Prius, a hybrid, outpaced that of the Ford Explorer, the top-selling SUV of the last 10 years, in 2007.

But at an average starting price of $21,500, the Prius is more expensive than most of its non-hybrid compact counterparts. The savings one gets from fewer trips to the pump will take years, if ever, to see actual overall savings.

While most of us would like to live the life of an economic crusader, many of us simply can't afford to. At least, we think we can't afford to. We've got bills to pay, and while it sure might feel good to drive around in a Prius, we can still buy a Ford Focus or Honda Civic for about $7,000 less.

However, going green doesn't always have to be an expensive project. According to Jeanie Pyun, editor of Sprig.com, a Web site dedicated to the green lifestyle, there are many ways to save green by going green.

"A lot of people come across on little things and they learn more and more and more and then, before you know it they are seeing green traits in products," said Pyun. "It could be something that they seek out because it's less toxic, it’s better for you, it tastes better or the quality tends to be better."

Trade In Those Old Gadgets

Throwing away old computers, cell phones and other gadgets can be very harmful to the environment because of the chemicals they can deposit in landfills. But there are places you can go where you can turn in your old gadgets and get cash back in return.

One Web site dedicated to this is CellForCash.com, which will take you old cell phone and give you cash in return. How much money you can get varies depending on the type of phone. Most phones listed on the site are recycled for free, but some earn rewards of more than $60.

"They will dispose of it for you in an environmentally responsible way, so by being green you are actually making money," said Pyun.

Other large retail stores like Best Buy will take your old computer and give you a discount on your upgrade.

"You could save like $58 on a Mac upgrade. So, you are actually making unexpected money," said Pyun.

Go Florescent

Buying a compact florescent light bulb will be more expensive than a regular bulb, but florescent bulbs tend to last longer and will save you money in the long run. A compact bulb can cost around $5.

According to Popular Mechanics, the average US household has 45 light bulbs. A compact florescent bulb can potentially use one-third the electricity of a regular bulb and last up to nine years, so replacing all your bulbs can save up to $180 a year.

"It can decrease your energy usage for light bulbs by nearly 75 percent," said Pyun. "And if you’re a little lazy, like I am, you never have to change them. They never die. I have light bulbs in my house that have been going for five years, and I am used to pulling out my step ladder and changing bulbs, but I haven’t had to do that for a very long time. So they save you a lot of money over time."

Unplug If It Isn't In Use

By taking a few minutes to unplug electronics that aren't in use around your house, you can save on your electric bill.

"Home electronics use a vast majority of power when they are turned off. You have to unplug them because they kind of sip off the energy grid the whole time," said Pyun. "And you’re paying for that. So if you go around unplugging things, it can have a big impact on your utility bill."

According to environmental activist Laurie David, founder of StopGlobalWarming.org, Americans spend more money on their utility bill paying for electronics when they are turned off than when they are in use, and unplugging them can save hundreds of dollars a year in energy costs.

Low Flow

Switching to low-flow shower heads and toilets can also cut dollars off of your monthly utility bills.

"It’s a good idea to go low-flow because -- particularly in the shower -- you are using water that gets heated by your heating system, and you’re paying for that twice," said Pyun. "So, that can have a big impact as well."

Say 'No' To The Brawny Man

Many people use paper towels to clean up around the house, weather it's for dusting or wiping down the kitchen counter. But think of how many sheets of towels one goes through in a lifetime. By switching to rags for around-the-house cleaning, you can save trees and dollars at the same time.

"Something that’s a lot cheaper in the long run is to buy a reusable cloth, like buy Skoy clothes for $4, and reuse them as you clean the house," said Pyun.

Tint Those Windows

Tinting the windows on your home can really cut down on the amount of AC you will have to use.

Getting your windows tinted professionally can cost around $5 to $7 per square foot.

"The payback for that is about three years, sometimes four years," said Harrison Hung of TintCenter.com. "The life of the window film is around 15 years, so you get 11 years of cost savings."

Get Uncle Sam To Pitch In

Upgrading your house with new doors and windows will help you save on energy costs, and Uncle Sam will even pitch in.

"You can get government tax discounts when you make home improvements that save you energy, like new windows and doors," said Pyun.

The tax breaks and deductions for green home improvements are a result of the 2005 Energy Policy Act.

According to the Energy Policy Act, "Consumers who purchase and install specific products, such as energy-efficient windows, insulation, doors, roofs and heating and cooling equipment in the home can receive a tax credit of up to $500 beginning in January 2006. The EPACT also provides a credit equal to 30 percent of qualifying expenditures for purchase for qualified photovoltaic property and for solar water heating property used exclusively for purposes other than heating swimming pools and hot tubs. The credit shall not exceed $2,000."
