The Evolution and Future Growth of Renewable Energy

Posted by 5 June, 2014 (0) Comment

In 2014, major debates and discussions surrounding climate change and green living in the United States has placed an unprecedented focus on renewable energy. The future growth in the renewable energy sector is slated to be significant as American’s make an effort to minimize their energy footprint on Earth.

While the support and evolution of renewable energy technologies is growing rapidly in 2014, supporters of renewable energy have been considering and exploring such technologies for close to a century.

For instance, the technological growth during the World Wars lead to the military exploring different renewable energy sources. In the 1950′s, solar power began to be developed, with the first high power solar cell made of silicon developed in 1954. It provided 6% efficiency, with a cost of $286/watt.

The early 1970′s marked further interest, as the Club of Rome think tank published a report stating that Earth has finite resources.

During the 1980′s, a 1 megawatt solar power station was built in California. This was the first facility designed on a utility scale.

Nuclear power had been considered a serious possibility for clean energy, though the 1986 Chernobyl nuclear incident cast doubt on this as a viable energy source.

Throughout the early 2000′s, talk and use of renewable energies has increased significantly, with an 8% use in 2007 in the US. Europe also saw an increase, with a 62% new power generating capacity in 2009.

There are several indications of positive future trends when it comes to clean, renewable sources of energy. These include the following:
*Importing of net energy in the US has decreased since 2012, by 15%, while there has been a 13% increase in renewable energy production within the US since 2012.
*There are 80,700 workers in the field of wind power, as of 2012, 25,000 jobs in the geothermal field, and 70,400 jobs in the field of biopower. Also, other careers have seen an upward trend in recent years.
*This is a global trend, with 5.7 million workers who work in the field of renewable energy. There is currently a shortage of workers in these fields, so an increase in technical training is necessary.
*2030 is the year that is being focused on for projected growth of trained professionals in these areas, and increased use of these energy sources.

A Robot that Cleans Solar Panels

Posted by 8 April, 2014 (0) Comment

By Tom Lombardo, Engineering.com

Deserts are ideal locations for solar farms – they get a lot of sunshine and the land is relatively inexpensive. On the other hand, their arid nature means that a lot of sand flies around, and sand on a photovoltaic panel blocks valuable sunlight, decreasing its output. Depending on location and weather conditions, dusty panels could decrease solar farm production by 3% to 15% in a given month. Periodic cleaning ensures that the panels get as much light as possible, but it’s a labor intensive process that may not pay for itself.

Ecoppia, an upstart company out of Israel, has an innovative, water-free solution: the E4 robotic PV cleaning system that dusts the panels using a self-cleaning microfiber cloth.

GeniusHour Leads to Solar Idea

Posted by 26 January, 2014 (0) Comment

Kiran-Ty

Ty Van De Motter and Kiran Krishnamurthi are two seventh graders at Ballard Brady Middle School in Pepper Pike, OH. During GeniusHour in Mrs. Lee Pop’s 7th grade Language Arts class they came up with an idea to build a solar lawn mower. GeniusHour is about an hour a week where the students can build whatever they want. It’s an idea that actually got its start at Google where they gave their employees 20% of their time to work on whatever they like.

Kiran and Ty believe that solar energy will play a big role in our future. They explain in their own words -

“Every year our world becomes more eco friendly. People come up with eco friendly cars and eco friendly heating systems, but what about an outdoors activity that works with the environment? Mowing your lawn! People complain about how it is too hot outside to mow the lawn, but they don’t focus on the benefits. All that radiant heat from the sun can be converted into a great source of energy, solar energy. When people mow their lawn they are outside in the sun. The sun’s energy can charge a solar panel. Our plan is to build a lawn mower that is powered by a solar panel. We will be connecting the panel to a battery so it does not blow up in our face. The panel will charge on its own but it can also be charging while people mow their lawn. We believe that this type of technology will “finish off” the gas-powered lawn mower.”

Kiran and Ty are currently writing to local business for sponsorships. They expect to finish their product before the end of the school year in June. If you would like to contact them please email them at kirankrishnamurthi11@gmail.com.

Best of luck boys!

KYOCERA Solar Captures Sun and Creates Shade at Tucson Airport

Posted by 19 December, 2013 (0) Comment

tn

Scottsdale, AZ – December 19, 2013 – As the holiday travel season begins, Kyocera Solar Inc. today announced that its industry-leading solar modules were selected to power the first phase of a 2.5MW parking lot canopy installation at Tucson International Airport. The 1MW first phase of the photovoltaic (PV) array, which offsets about a fifth of the terminal complex’s total power needs, is now operational and a dedication ceremony will be held at 11 am Mountain Time, December 20.

The project converts the abundant sunshine in “The Old Pueblo” into renewable energy powering the airport’s main terminal. It’s part of the airport’s ongoing environmental efforts, utilizing $5.7 million in funding awarded by the Federal Aviation Administration and $280,000 contributed by the Arizona Department of Transportation to offset a federal grant matching requirement.

Collaboration with Natural Power & Energy helped ensure that the system was properly sized for the airport’s power output and glare avoidance requirements. By working closely with Tucson-based contractor Barker-Morrissey Contracting, the Design-Build team was able to meet the tight installation deadlines of the 5-acre first phase with time to spare.

“Airports are an ideal location for solar canopies because of the large amounts of space they can cover, additionally serving as desired shade to cars parked for hours or even days,” said Steve Hill, president, Kyocera Solar Inc. “We are glad to have completed this first phase before the busy travel season; it’s a nice holiday bonus to know that part of the electricity usage in the main terminal is being offset by the parking lot’s large solar array. Kyocera Solar is proud to power this important project in our home state.”

The solar canopy structure is a 20-foot tall curved, open-lattice design comprised exclusively of efficient, durable Kyocera modules that create shade for parking spaces. Vegetated “green walls” are also planned, which will use live plants to create a cooling microclimate effect in the parking area. There is no additional charge for the parking spaces under the solar canopy.

This project’s federal grant is part of a program that provides funding for airport projects that promote energy efficiency under the FAA Modernization and Reform Act of 2012.

“Kyocera’s responsibilities with every project are to assist throughout the lifecycle of that installation,” Hill stated. “Our technical expertise in addition to our 38 years of high quality module production experience adds value and can help reduce project costs. Kyocera’s success depends on our customer’s success.”

Construction on the main public parking lot began in May 2013, kicking off a three-phase installation expected to be completed in 2-3 years. Work has already begun on phase 2 in the remaining 7 acres of the parking area.

Tucson joins Chicago’s Midway as another major airport going green with Kyocera. Midway’s Quick Turn Around rental car washing and refueling facility was outfitted with Kyocera photovoltaic solar modules in October 2013.

Clean Energy Collective Powers Up Three More Utility-Scale Community-Owned Solar Facilities

Posted by 16 October, 2013 (0) Comment

CEC_Breckenridge_Arial

BOULDER, COLO. – (October 15, 2013) Three new community-owned solar PV facilities by community solar pioneer Clean Energy Collective (CEC) began delivering power to ratepayers in Colorado this week, bringing to 10 the number of shared utility-scale arrays operating in the state. An additional 10 facilities, about 5 MW, are in the development pipeline for Colorado.

The resort town of Breckenridge, Colo. is now host to two 500 kW community-owned solar facilities that will serve Xcel Energy customers in Summit County. Both systems were sold out before construction was complete. A 400 kW community-owned system perched on a former Air Force hangar is also now delivering clean power to Denver County ratepayers. Combined with the 106 kW original array on the historic Hangar 2 building, this creates the nation’s largest building integrated PV (BIPV) installation at over 500 kW.

Introduced in 2010, CEC’s community-owned solar model (COS) was designed to provide every ratepayer in a utility territory the opportunity to purchase individual solar panels in a shared, locally-sited, utility-scale array. This innovation opens up solar PV ownership to renters, people in multi-dwelling buildings, properties with poor solar exposure, and individuals of all income levels. Because they are sited and maintained for maximum production, utility-scale facilities provide more energy for longer than smaller, individual systems, allowing for a faster and greater financial return.

“Our model is not supplanting people who want to and can put solar on their house, but rather opening the market to the other 75% of electric users who have until now faced insurmountable barriers,” said CEC founder Paul Spencer.

While community solar makes PV energy available to everyone on the grid, real traction for rapid deployment has come from its broad appeal for utilities. Large IOU’s, municipal utilities, and rural cooperatives can add solar to their mix with a turn-key solution. It provides in-network, reliable, utility-scale clean energy generation at reasonable power rates that applies nicely to RPS requirements without capital outlay or responsibility for monitoring, customer administration, operations and maintenance.

CEC has partnered with six utilities so far in Colorado, including 11 facilities rewarded through Xcel Energy’s Solar*Rewards Communities program. Once complete, access to solar ownership will be available to more than 95% of Colorado ratepayers. CEC has also installed the state’s first community-owned solar gardens for New Mexico, Minnesota, and Vermont, and has topped $40 million in facility developments.

“CEC has cracked the code, opening a consumer solar market that is four-times larger than the onsite solar marketplace as we have traditionally known it,” said Nikhil Garg, Vice President of Black Coral Capital, a Boston-based investment firm focused on cleantech and alternative energy.

About Clean Energy Collective (CEC)
Colorado-based Clean Energy Collective is a developer of community-based renewable energy facilities and a national leader in community power generation. CEC pioneered the model of delivering clean power-generation through utility-scale facilities that are collectively owned by participating utility customers, establishing the first community-owned solar garden in the country near El Jebel, Colorado. Today, CEC has 23 community-owned facilities online or in development, representing more than 10 MW of community-sited clean energy.

Alta Devices Enables Unmanned Aircraft to Fly as Long as the Sun is Shining

Posted by 27 July, 2013 (0) Comment

Alta Devices solar-powered unmanned aerial vehicle

Very High Efficiency and Lightweight Solar Material Provides Unmatched Power to Weight Ratio

SAN FRANCISCO, CA – July 25, 2013 – During a keynote at the small unmanned systems business expo in San Francisco, CA today, Alta Devices’ CEO, Christopher Norris, explained that small unmanned aerial vehicles (UAV) are no longer constrained to short-range or limited flight times and are now able to fly as long as the sun is shining. This is expected to have tremendous economic value for agricultural, public safety, wildfire mapping, search and rescue, law enforcement, industrial applications, and many others.

In the past, solar solutions for powering these vehicles were either too heavy or could not produce enough power for long-range flight, or both. However, a small UAV outfitted with Alta Devices’ mobile power technology can produce enough power, while adding practically no weight, to fly indefinitely under the sun.

Alta Devices manufactures the world’s thinnest, most flexible, and most efficient solar material. It can be used on anything that moves, can be carried, or worn, to generate substantial power from light. In the case of a typical small UAV with a 9-foot wingspan, Alta’s material can generate roughly 125W of power and weigh about 125g (about 4.5 ounces). In many cases, this is enough power to sustain flight and keep an on-board power source fully charged.

Chris Norris, Alta Devices president and CEO explained, “A broad range of civil unmanned systems will benefit from extended range and endurance. For example, when a UAV is used to map a wildfire, or on a human search and rescue mission, it is critical to have flight times that are as long as possible.” And for agricultural use, the ability to extend the range of a UAV and shorten the task of monitoring a large area by avoiding stops to recharge, has significant economic benefit to the farming community. According to a report published by the Association for Unmanned Vehicle Systems International (AUVSI), precision agriculture and public safety represent over 90% of the potential for civil UAS use and will result in an economic benefit to the United States of 82 billion dollars between 2015 and 2025.

Gretchen West, executive vice president, Association for Unmanned Vehicle Systems International (AUVSI) said, “Efficiency and endurance are the holy grail for unmanned systems. Enabling all-day flight times for small UAVs will change the game for civil use and represents a significant market opportunity.”
