China Leads Growth in Global Wind Power Capacity

Global installed wind power capacity continued to grow in 2011,  according to new research conducted by Worldwatch Institute Vital Signs Online service. The data collected showed that global wind power capacity topped out at 238,000 megawatts (MW) after adding just over 41,000 MW. This means that the global capacity grew by 21 percent in 2011,… Continue reading China Leads Growth in Global Wind Power Capacity


Pumped Hydroelectric Energy Storage Technology

Pumped Hydroelectric Energy Storage (PHES) is a form of energy storage technique that is based on the storage of large amount of water at a high elevation. This is accomplished with two water reservoirs (artificial, lake or sea) which are at two different elevations (pressure heads), by pumping water from the lower elevation to the… Continue reading Pumped Hydroelectric Energy Storage Technology

Geothermal Potential in the Caribbean:

As explained in the post "introduction to geothermal energy", geothermal energy is heat energy originating from beneath the Earth’s crust. This heat is continually produced by the natural decay of radioactive materials such as uranium and potassium. According to US Department of Energy the amount of heat within 10,000 meters of Earth’s surface contains 50,000 times… Continue reading Geothermal Potential in the Caribbean:


Grid Level Energy Storage

Have you been wondering, like many, what is Grid Energy Storage and why is there so much talk about large-scale energy storage? Well, grid energy storage systems (ESS) are large-scale facilities used to store energy in some form or the other (electrical, chemical, potential, gravitational, etc) within an electric power grid. Energy is stored during times… Continue reading Grid Level Energy Storage

Intro. to Geothermal Energy

Geothermal energy is heat energy originating from Earth. The word itself was derived from the words geo and thermal meaning Earth and heat respectively. This heat from the earth is used in many ways, including as a source for electricity generation and to heat and cool buildings. Geothermal energy provides an affordable and sustainable solution… Continue reading Intro. to Geothermal Energy

Jamaica’s Hydroelectric Potential

Jamaica, the paradise island that is sometimes referred to as  “the land of wood and water,” has great hydroelectric potential due primarily to its many rivers, land topography and climate. Out of a list of 120 rivers, the Island has several rivers that are suitable for hydroelectric power generation. Hydroelectric power is power generated from water.… Continue reading Jamaica’s Hydroelectric Potential

Economics of a Small Solar Electric System

Small solar electric or photovoltaic (PV) systems are currently gaining popularity in the public domain in several Caribbean islands including Barbados and Jamaica as a result of spiraling electricity cost in the region. The cost of these systems, however, presents a huge drawback to consumers, thus forcing them to think twice before investing. When considering… Continue reading Economics of a Small Solar Electric System
