Why microrenewables?
by Roberto Verzola By microrenewables, we mean small-scale renewables, whose outputs are at kilowatt instead of megawatt levels. These include solar PV systems on home and building rooftops, microhydro facilities, small wind turbines, small biogas digesters, and other micro-systems. As a rough guide, we can use [...]
Why LED lighting makes sense
by Roberto Verzola Shifting to energy-efficient LED lighting is a good example of an energy efficiency measure and makes eminent sense, as the following calculations will show. Consider installing a 15-watt LED lamp for 250 pesos, to replace a 40-watt fluorescent lamp. The more efficient LED [...]
The CREST microhydro agenda
by Roberto Verzola The Center for Renewable Energy and Sustainable Technology (CREST) is hard at work on its microhydro agenda. It is partnering with Galing Pook awardee, the LGU of San Luis, Aurora, and other local governments on trials to bring down the capital expenses for [...]
Micro vs mainframe
by Roberto Verzola The micro/mainframe terminology is derived from the early debate in the computing industry between IBM Corp. and Intel Corp. IBM was the pioneer and leader in the computer industry of the 1960s, and faced only a few small competitors. The industry players were [...]
It is expensive to have no electricity
by Roberto Verzola Those who do not have access to electricity use candles or kerosene lamps at night. We will compare the cost of these lighting technologies to the cost of electric lighting. Assume that a candle as well as a kerosene lamp provide as much [...]
Exempt small-scale renewables from the bureaucratic mazes of electric utilities, city halls and the Energy Regulatory Commission
by Roberto Verzola Today, basically the same set of rules apply to small-scale renewable projects below 100 kW as well as to 100 MW projects. This is a huge disincentive for small-scale RE. The experience of the Romblon Electric Cooperative (Romelco) is a case in point. Their [...]
