To save a lot on energy, spend a bit first

If you're among the lucky few who still have a little cash, now may be a good time to invest in making your house more energy efficient. The federal government has sweetened the pot with expanded tax credits that will help offset the cost. Here's what you need to know about how incentives can help you:

Energy-efficient windows and doors, HVAC systems, insulation, roofing and hot water heaters

How it works: Helps reduce household energy use

What it saves: Depends. But the government's Energy Star office notes that adding insulation to your attic is one of the most cost-effective steps you can take.

Tax break: The federal credit will cover 30 percent of the cost up to a combined cap of $1,500. Ask your installer or check Energy Star's Web site before installing.

Geothermal heat pump

How it works: Uses the ground's constant 72-degree temperature to heat and cool the house.

What it costs: Two to three times more than a conventional system.

What it saves: Can cut your power bill by 50 percent.

Tax breaks and rebates: The tax credit will reimburse 30 percent of the cost of new systems. Ask your installer or check with Energy Star's Web site.

Solar electricity

How it works: Photovoltaic panels convert the sun's energy into electricity.

What it costs: From $30,000 to $45,000 for a five-kilowatt residential system.

What it saves: Allows the electric meter to run backward when the panels are producing power, reducing bills. Savings depend on the system.

Tax breaks and rebates: Florida offers a rebate of $4 per watt, capped at $20,000 for residential units. A tax credit covers 30 percent of the cost.

WARNING: The state's solar fund has run out of money. New applicants will be added to a waiting list.

Solar water heater

How it works: Uses the sun's energy to heat water.

What it costs: From $1,500 to $3,000 or more.

What it saves: Water heating accounts for 14 to 25 percent of a home's energy use. A solar heater can cut the energy used by 50 to 80 percent.

Tax break: Florida offers a $500 rebate for residential systems. Local utilities offer additional rebates. Contact your utility before installation and check to make sure the system qualifies for the federal tax credits. The credits reimburse 30 percent of the after-rebate cost of residential systems.

WARNING: The state's solar fund has run out of money. New applicants will be added to a waiting list.

  5. 'Garbage juice' seen as threat to drinking water in Florida Panhandle county


    To Waste Management, the nation's largest handler of garbage, the liquid that winds up at the bottom of a landfill is called "leachate," and it can safely be disposed of in a well that's 4,200 feet deep.

    Three samples that were displayed by Jackson County NAACP President Ronstance Pittman at a public meeting on Waste Management's deep well injection proposal. The sample on the left is full of leachate from the Jackson County landfill, the stuff that would be injected into the well. The sample on the right shows leachate after it's been treated at a wastewater treatment plant. The one in the middle is tap water.
