As discussed in this recent National Geographic article, the world's large solar energy plant, the Ivanpah Solar Plant, located in the Ivanpah Valley of California’s Mojave Desert, is nearing completion. When completed, the solar plant will contain 170,000 mirrors and produce 377 megawatts (MW) of power, more than double the previous record holder of 150 MW, and enough to power more than 140,000 homes. We hope that renewable energy megaprojects
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
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
100 Gigawatt Milestone 100 Gigawatts! Total worldwide installed solar capacity recently broke the 100 gigawatt milestone. With over 30 gigawatts installed in 2012 alone, it is clear that there is a new push for solar energy. We are excited to see the sector grow so quickly. Wind, often considered a more mature industry, broke the 100-gigawatt global capacity mark in 2008. Lets keep pushing our elected officials to promote
Flying on Solar Power The Solar Impulse, an idea born in Switzerland is a long range solar powered aircraft flying across America. It's composed of lithium polymer batteries, a 10 hp (7.5 kW) motor, a twin-bladed propeller, and 11,628 photovoltaic cells. The plane seats one. According to the Associate Press, this is the first attempt by a solar plane flying both day and night without fuel to fly across
The main difference between a brushed motor and a brushless motor, (besides the differences implied by the names), is that the brushed motor uses an electromagnet system as the rotor surrounded by permanent magnets (and sometimes more electromagnets), and the brushless motor has a magnetic rotor surrounded by electromagnets. A brushless DC motor (BLDC) is a DC (direct current) electric motor that uses an electronically-controlled commutation system, instead of a
