We all waste more energy than we like to think about. Because wasted renewable energy is still wasted energy, we need to maximize our energy efficiency before we invest in renewable energy sources for our homes & businesses. The cheapest unit of energy is the one we don't need to burn at all. Read on to get started.

Legislature Overrides Veto to Help Restore Efficiency Maine Funding
07/01/2015 - 8:31pm

And image courtesy of Maine Association of Building Energy Professionals.L.D. 1215, the bill that restores the missing word "and" that was omitted from the 2014 Omnibus Energy Bill and reverses the ruling by the Public Utilities Commission to cut Efficiency Maine funding by $38 million, is now law.

On June 23, 2015, the governor vetoed the bill. First the House voted 144-0 to override the veto, then the Senate voted to do the same, 35-0. The Public Utilities Commission will be asked to reconsider its vote in light of the new legislation and set the funding level at the intended $60 million.

Bowdoin College Earns EPA Award for Energy Efficiency Efforts
07/01/2015 - 4:42pm

Solar panels atop Bowdoin's Farley Field House and Watson Arena Image courtesy of Bowdoin CollegeOn July 1, 2015, Bowdoin College in Brunswick, Maine was recognized by EPA with a 2015 Energy Star Combined Heat and Power (CHP) award. CHP technology produces electricity and useful heat simultaneously from a single energy source, such as natural gas, oil, or biomass. For hospital systems and universities, CHP systems can also provide reliability benefits which ensure that these facilities’ operations can continue in the event of power outages.

This award recognizes Bowdoin College for the superior efficiency of its CHP system that produces 630 kW of electricity and steam that provides space heating and hot water to 1.4 million square feet across 56 campus buildings. Bowdoin’s CHP system, designed by RMF Engineering, includes an oil or natural gas-fired boiler and a 630 kW steam turbine. With an operating efficiency of nearly 87 percent, the CHP system requires approximately 12 percent less fuel than grid-supplied electricity and conventional steam production. The system also avoids emissions of air pollutants, including an estimated 1,000 tons of carbon dioxide annually, equal to the emissions from the generation of electricity used by nearly 130 homes.

King Proposes Bill to Promote Personal Energy Independence
06/01/2015 - 12:20pm

Senator Angus King of Maine image courtesy of Angus KingOn May 6, 2015, Senator Angus King of Maine introduced The Free Market Energy Act of 2015, which would establish a set of parameters for the governance of distributed energy resources (DER) such as solar power, stored energy or demand response. Existing policies discourage investment in DER. For example, utilities may levy expensive grid-connection fees on consumers who pursue newer technologies, while current net metering formulas may not properly compensate grid owners when these new technologies are connected.

The proposed act would protect the right of consumers to connect their distributed resources to the grid for a reasonable price while also ensuring that grid owners and operators receive proper compensation to maximize the potential of DER in relation to the grid. The act would also retain the authority of each state to design its own set of rules within its parameters, to properly reflect the state’s needs.
