When you think of the word’s largest power plants, you probably don’t think renewable energy. However, we can thank hydroelectric, the often forgotten renewable resource, for the world’s four largest power plants. In the graph on the left, you can see how dominant hydroelectric is compared to other renewable resources. We should be excited about the great growth in solar and wind recently but must not forget about our largest
Reviewing the solar panels on the Solar Impulse, the solar plane currently flying across the country, allows us to look at solar efficiency in a new way that not only could effect solar flight but also ceiling exhaust fans and roof fans. The solar panels on the plane are not the best at converting light energy into electric power by area covered, but do excel in terms weight. The lightweight
According to a report by U.S. Solar Market Insight, the US had a record first quarter with 723 MW of solar photovoltaics installed in Q1 2013. This represents a 33 percent increase over Q1 2012 and brings the cumulative US photovoltaic capacity to 7.9 gigawatts. This growth was led by residential installations, which experienced a 53% increase over the same period. Prices for residential systems fell below five dollars a
While photovoltaic cells are certainly one of the best ways to produce clean energy, from a scientific perspective they are actually quite inefficient. In the average solar cell, only about 20% of the solar energy is transferred into usable electricity. This is in contrast to photosynthesis performed by plants, which reaches efficiencies of 95 percent. While in the past, we knew very little about how plants reached these efficiencies, new
On July 4, 1776, we claimed our independence from Britain and Democracy was born. Every day thousands leave their homeland to come to the “land of the free and the home of the brave” so they can begin their American Dream. The United States is truly a diverse nation made up of dynamic people. Each year on July 4, Americans celebrate that freedom and independence with barbecues, picnics, and family
Solar Advantages Tesla debutes Tesla Motors has introduced a system is says will allow a swap of a car's battery pack in less time than it takes to fill up a traditional car's gas tank. At a demonstration of the system in California, Tesla chief Elon Musk said battery swap stations will be installed throughout a network of "supercharging" stations the company is installing around the nation, CNN reported Friday.
Energy consumer of the future; kitchen exhaust fans, house attic fan and solar attic fans an International first.
Energy consumer of the future Six Dutch companies, three knowledge institutes and 40 households will initiate a pilot in Groningen and Hoogkerk in which consumers will be testing innovative, smart energy services related to sustainable energy choices and cost savings. The objective is to investigate which smart energy services best meet the consumer's requirements, in order to implement a sustainable and cost effective energy supply. This is the first
Solar Energy Advantages As reported by ABCNEWS: A Following Hurricane Sandy, you would find citizens of New York City and other affected areas waiting in long lines outside Starbucks and other restaurants are not waiting to buy food, but vying for a chance to charge their cell phones. The city of New York is attempting prepare for its next emergency by installing solar powered low draw phone chargers throughout
World's Largest Solar-Powered Boat Comes to Boston Its mission to build stronger relationships between scientists, entrepreneurs and innovators in Massachusetts and Switzerland, swissnex Boston is welcoming the world's largest solar-powered boat to Boston's Fan Pier for its inaugural visit, June 22-26. The first boat to travel around the world exclusively powered by solar energy, the MS Turanor PlanetSolar features 29,160 solar panels and produces zero gasoline or CO2 emissions. The
MITs Solar System Scientists mapped 17,000 rooftops in Cambridge, Mass., providing residents with a web interface to look up their homes and project the cost and return on investment of photovoltaic solar panels. Using satellite imagery and Light Detection and Ranging (LiDAR) data from a previous aerial survey to create a 3-D model of Cambridge. Then the team charted the exact shape of rooftops and possible sunlight obstructions, such
