The renewable energy (RE) industry is growing rapidly, and a wide variety of employment opportunities -- from system design and installation to hardware development and engineering -- are opening up on a regular basis. The first step in finding a career in RE is to assess what skills you have, what skills you'd like to learn, and what type of position would be most satisfying.
Solar Energy International (SEI) has released a book that should help builders and contractors figure out the best way to incorporate solar photovoltaics (PV) into new construction. Designing, installing and maintaining such systems requires knowledge and training, SEI stated in a press release.
Solar hot water manufacturer Heliodyne is now offering web-based solar installation courses for trade professionals interested in installing solar thermal systems.
[RenewableEnergyAccess.com] Solar Energy International (SEI) is coming to Hawaii to offer two renewable energy workshops in Honolulu in partnership with Inter-Island Solar Supply. First, a one-day Introduction to Renewable Energy session, on Saturday, February 5, will give participants an overview of solar, wind and water power. This will be followed by a six-day intensive hands-on Photovoltaic (PV) Design & Installation […]
Solar power in action in the home in Maryland and Virginia is the focus of a series of television programs set to air nationwide in March on Home & Garden TV's companion channel, the Do-It-Yourself Network. The series, called Solar Solutions, is a follow-up to the Solar Decathlon competition held on the National Mall in Washington, D.C. in September.
The feed-in tariff scheme, allowing people to sell electricity back to the grid, is likely responsible for the tremendous growth of solar power the last two years. Since it was first launched in 2010, a little over 22 months ago, solar panel installations in homes, schools and fields all over UK has grown by a whopping 41 times. The 1,000 […]
Solar panels are devices that produce electricity from sunlight. People also call them solar modules. Solar panels can be the cure to your expensive electric bills. In some states home solar power can save their owners over $50,000 in avoided electricity costs over 25 years. You can see your solar panel cost and discover more on the topic what is solar power by visiting solarreviews.com.
Raw Materials for Wood Pellets: round wood, wood logs, wood slabs,.wood branches, wood chips, wood shaving, wood sawdust, wood leaves, wood waste from sawmill, etc. Wood Pellets Making Equipment: wood crusher, wood sawdust dryer,wood pellet machine, wood pellet cooler, automatic packing machine Description for Wood Pellet Produce ProcedureIn industries, the procedure of wood pellets production mainly departs in the following steps: wood material crushing, water moisture control, biomass pelletizing, wood pellets cooling, wood pellets weighing and packing. In a wood pellet line, the pelletizing process is the most important. Equaling to the pelletizing part, the die and the roller is the most important part in a pellet machine. wood material crushing:As a general rule, the size of raw material should always smaller than the pellets size. For wood logs or round wood, crushing process by a wood crusher is needed. Then the smaller wood blocks will be fed into the wood chipper to chip the wood into chips for further use. If you want to make pellets with a size of 6mm, or smaller, you will need a wood hammer mill to make the wood chips into wood sawdust with a size not bigger than 6mm.water moisture control:To make premium wood pellets, the water moisture of the raw material should be about 12%. So it is necessary to remove excess water from the raw material. In industrial pellets production, a wood pellet cooler is usually adopted. For small-scale, You choose to dry the material in the sun or other methods.biomass pelletizing:Wood material through a feeder come into the pelletizing room, where the die and the rollers are motioning relatively at a high speed. With the extrusion force and the high temperature forming in the relative motion, the intermolecular forces in wood material molecule have changed. Thus the plasticity of the wood materials has increased. Then the materials are shaped into pellets by the hole on the die and pushed out. wood pellets cooling:The pellets come out of the pellet machine is hot and wet. A pellet cooler is used to bring the temperature down and reduce the water content. After cooling, they are harder and easier to store or transport.wood pellets weighing and packing:A wood pellet packing machine can pack the pellets in plastic bags with the same weight for transport or for sale. For a large quantity of wood pellets, bulk trucks are need. Bulk pellets are loaded from the pellet mill directly into trucks for delivery to bulk storage containers. The bulk trucks are more expensive than regular flatbed trucks, but a much more efficient system of processing.
Wind power has seen dramatic growth in recent years and remains a highly topical and highly politicised sector. It plays an important role in Europe's economy, contributing to its gross domestic product (GDP) and job creation. Ernst & Young, for example, estimates that for every €1 million invested in wind, twenty-one jobs are created.
