Conventional energy sources and pollution: one actual problem. The development small power machines with high efficiency and low emissions. The intensive capital movement from centralized generation plants to high risk plant smaller, less expensive and closer to final consumers. The signing Kyoto Protocol was that national governments began to take measures to reduce CO 2 emissions and greenhouse gases by promoting energy efficiency.
The Cuban Electric National System (SEN). Load Power cover plants by SEN in on Cuba typical in day 2004. in July 2005.
The Cuban Energy Revolution: more than 20 programs. Fault maintenance. First stage: Diesel gen sets installed. Power plants so far load centers. Strengning economic blockade against Cuba. Limited access to international markets. High Price oil. To increase number hurricanes that affected country. Second stage: Fuel oil gen sets installed.
Benefits DG in Cuban SEN. More than 580 thousand actions to improve technical condition distribution networks, including elimination double transformation where it is possible, permitted to reduce energy losses in distribution network upto 11%.
