Did we even need to drill the Deepwater Horizon oil well to begin with?  Actually, no. There are over 100 million homes in the U.S. Most of them use energy inefficiently because they’re not well insulated, sealed and set up.  The energy contained in the biggest oil spill in U.S. history is equal to the energy that just 75,000 homes waste in a single year.

Seventy-five thousand homes represent less than 0.1 percent of all single-family homes in the U.S. or the number of homes in a single mid-sized U.S. city, like Providence, R.I., or Chattanooga, Tenn. Doing energy retrofits to make those homes efficient would save the equivalent of the entire Gulf Oil Spill every year on a permanent basis.

Comparing the Costs

No one really knows how much it’ll end up costing to clean up the disaster created by the Gulf Oil Spill. And when a final number is calculated, years from now, there’s no way that it’ll take into account the true extent of the environmental damage that the oil spill has created. But even in the preliminary estimates made before the oil has finished flowing, the cost is expected to exceed $40 billion.

How does that compare to doing 75,000 home energy retrofits? (more…)

First off, a few burning questions… Have high upfront costs derailed your renewable energy or energy efficiency projects? Would receiving positive cash flow from day one make your clean energy project more attractive? Are you worried that it may be difficult to recoup your investment in clean energy if you sell your property?

To resolve these issues and accelerate the implementation of energy upgrades to commercial and residential property, cities and counties across the nation are offering PACE, a new financing model for clean energy projects.

To learn more about how PACE works and how it can benefit businesses and homeowners, I recently spoke with Dennis Tsu, who manages Business Development for Commercial PACE with Renewable Funding. Based in Oakland, Renewable Funding is the leader in the turnkey administration of PACE programs.

What is PACE?

William Dinkel: Could you please provide a brief summary of PACE programs for our readers?

Dennis Tsu: First off, PACE is an acronym for Property Assessed Clean Energy. The basic concept is to allow residential and commercial property owners to borrow money from their local governments to use for making energy efficiency or alternative energy improvements to their properties, and then to pay that money back through a (more…)

These are the tips that keep coming up from a few solar pros in the community.  They can be common sense but tend to be overlooked by most folks who are pondering installing a solar panel system:

1. You can save money by learning about solar energy yourself

Now that solar panel parts are readily available for purchase on the internet, it really is possible to save money by building your own solar panels.  Build a few to power small battery powered electronics equipment like your laptop and cell phone.  Use those project to learn about how solar energy works, and to find out if you enjoy the process enough to tackle building them on a larger scale.  If you find you enjoy building solar panels, design a system for larger scale solar energy applications. 

2. Solar energy systems are scalable 

Many people think that in order to use solar power in their homes that they have to build and install a complete solar electric system that will supply all of the electricity that they now use.  But that’s simply not true.  You can start off by using smaller solar panels to power outdoor lighting or to light the inside of your garage.  Or you can install a small grid-tied solar panel system to offset part of the electricity that your family uses on a daily basis to cut your energy costs and reduce your carbon footprint.  Later you can add more solar panels and eventually generate enough solar electricity to be energy independent or even sell electricity back to your local utility company. 

3. Do an energy audit before you (more…)
