When the biological waste inside landfills becomes trapped without exposure to air, it undergoes anaerobic decomposition and produces organic compounds, such as methane (CH4). Landfills are the largest source of […]
Continue reading...Hydroelectric power is generated by capturing the kinetic energy or motion in free-flowing or falling water, waves, currents or tides, and converting it into electric current. The Massachusetts Class I Renewable […]
Continue reading...Capacity issues—whether funding or staff time—can be a recurring obstacle for local clean energy efforts. The additional responsibilities and specialized knowledge necessary to pursue such efforts can be overwhelming for busy […]
Continue reading...Geothermal energy technology captures heat energy stored in the Earth’s crust and converts it into electric or heat energy. Geothermal resources can be tapped at multiple depths, ranging from low-temperatures […]
Continue reading...Electrochemical fuel cells convert fuel directly into electric current by triggering a chemical reaction between the fuel and an oxidant using an electrolyte. So long as the fuel (reactant) and […]
Continue reading...Before identifying energy goals, and consequent strategies to reach those goals, communities must first develop an energy use profile of the community as a whole, including the municipal, residential, commercial […]
Continue reading...Collaborating with students can be an efficient and low-cost way to build greater capacity for clean energy efforts. Through an internship program, students can apply their academic knowledge and experiences […]
Continue reading...Efficiency is a broad concept that refers, in general, to the elimination of waste. The efficiency of a system is measured as a ratio of the useful work it produces […]
Continue reading...Municipalities interested in solar have multiple options for pursuing it, including direct ownership, community shared solar, or a power purchase agreement (PPA). Each approach to solar has different potential risks […]
Continue reading...Everything requires energy to respire, move, grow and reproduce. Most energy on Earth is originally derived from the sun, the only input into an otherwise closed and self-sustaining system. In […]
