Has the global economic crisis got you feeling more blue than green? If so, you’re not alone.

U.S. consumers are pulling back spending on everything, and carbon-cutting products like hybrid cars and solar panels are no exception. After all, being green often requires us to pony up big chunks of change with the promise of cost savings later. That pitch, according to many green business owners, isn’t working so well these days.

“People are so scared about the future that they don’t want to commit to paybacks that have too long a window,” said Alan Finkel, owner of Santa Monica-based Green Life Guru, a company that helps homeowners reduce their gas and electricity usage.

A sharp drop in oil prices since this summer hasn’t helped the trend. After all, who needs a hybrid car when fill-ups cost less than $20 a pop?

Of course, there are ways to be green without spending money. We can drive less, recycle more, and resist the urge to crank up the thermostat.
