Why Fluorescent Lamps Must Go

Lighting is one of the most important devices in homes, buildings and learning facilities. The provision of lighting allows us to extend our social and economic activities. It offers protection and security to individuals and families. However lighting devices are not created equal.

Asian Development Bank should close its doors to all dirty energy

Climate groups and communities advocating against coal projects in the Asia-Pacific region have welcomed the Asian Development Bank’s (ADB) recent draft energy policy that aims to stop financing coal power and mining, and extraction activities for oil and natural gas. However, if not monitored closely, ADB could also be jeopardizing its own efforts by creating loopholes in its new policy that might still allow financing for fossil gas and other dirty energy facilities.

Bi-directional meters enable net metering … not!

Uni-directional electric meters are like electrified barbed wires that confine villagers inside a hamlet. Utility customers are locked in, unable to take advantage of the cheap solar electricity that one gets from a simple grid-tied configuration. Anyone who tries climbing over the wires gets electrocuted. Instead of enjoying solar savings, they are punished severely and charged for trying to share their surplus with neighbors.

Micro vs mainframe

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 often described as “Snow White and the seven dwarfs”.

Exempt small-scale renewables from the bureaucratic mazes of electric utilities, city halls and the Energy Regulatory Commission

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 20-kW hybrid facility in Cobrador Island, which involves a mixture of solar power, battery storage and diesel generator back-up, also had to go through essentially the same bureaucratic maze at the Department of Energy and the Energy Regulatory Commission as 100 MW solar farm projects.

Why microrenewables?

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 the government limit of 100 kilowatts and below.

The CREST microhydro agenda

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 microhydro installations below the capex of mini- and mega-hydroelectric projects.

Why LED lighting makes sense

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.
