What Is Energy Harvesting – Why Is It Needed?

The process of extracting small quantities of energy from one or more natural, inexhaustible sources, accumulation and storage for subsequent use at an affordable cost is called Energy Harvesting. Specially developed electronic devices that enable this task are termed Energy Harvesting Devices.

The world is facing acute energy crisis and global warming, stemming from rapid depletion of the traditional sources of energy such as oil, coal, fossil fuels, etc., which are on the verge of exhaustion. Not only is the global economy nose-diving, but the damage to the environment is also threatening our very existence. Natural calamities like earthquakes, tsunamis, droughts, floods, storms, etc., have become the order of the day. Economic growth is generating a spiraling demand for energy, goading us to tap alternative sources of energy on a war footing. Our very existence on the planet Earth is at stake, and we must find immediate solutions to meet the energy needs for survival.

Alternative Energy Sources Available

There are many, almost inexhaustible, sources of energy in nature. In addition, these energy forms are available almost free, if available close to the place where required. Sources include: Solar Energy, Wind Energy, Tidal Energy, Energy from the waves of the ocean, Bio Energy, Electromagnetic Energy, Chemical Energy, and so on.

Recent Advances in Technology

The sources listed above provide miniscule quantities of energy. The challenge before us is to gather the miniscule amounts and generate meaningful quantities of energy at affordable cost. Until very recently, this has remained an unfulfilled challenge.

Today, research and innovation has resulted in creation of more efficient devices to capture minute amounts of energy from these sources and convert them into electrical energy. Besides, better technology has led to lower power consumption, and hence higher power efficiency. These have been the major propelling factors for better, more efficient energy harvesting techniques, making it a viable solution. These solutions are considered to be more reliable and relatively maintenance free compared to traditional wall sockets, expensive batteries, etc.

Basic Building Blocks of an Energy Harvesting System

An Energy Harvesting System essentially consists of:

a) One or more sources of renewable energy (solar, wind, ocean or other type of energy)
b) An appropriate transducer to capture the energy and to convert it into electrical energy (such as solar cells for use in conjunction with solar power, a windmill for wind power, a turbine for hydro power, etc.)
c) An energy harvesting module to accumulate, store and control electrical power
d) A means of conveying the power to the user application (such as a transmission line)
e) The user application that consumes the power

With advancement in technology, various interface modules are commercially available at affordable prices. Combined with the enhanced awareness of the efficacy of Energy Harvesting, more and more applications and utilities are progressively using alternative sources of energy, which is a definite sign of progress to effectively deal with the global energy crisis.

Optional addition of power conditioning systems like voltage boosters, etc., can enhance the applications, but one must remember that such devices also consume power, which again brings down the efficiency and adds to cost.

We love finding products that make great use of solar electricity and our electronic components. How about a solar powered LED light in a mason jar? Perfect for your backyard porch or for mood lighting at a party – or even as a night light in your bathroom, bedroom or kitchen!

The ones we found at MyGrillfriend.com give you a choice – it can be a soft deep orange colored light (referred to as a ‘sun jar’) or a beautiful shade of blue (called a ‘moon jar’) just by flipping a switch. The solar panel inside the jar collects the sun’s rays during the day, and automatically turns on when the lights go down. So easy to use and the LEDS will burn for years! Can I just tell you how much we love this product?!

Of course we had to take our Sun & Moon light apart to see how they made it. Nestled inside the neck of the jar is a highly efficient solar cell which is attached to a rechargeable battery and two low power LEDS – one blue and one orange. On the bottom of the insert is a diffuser which spreads the light throughout the frosted glass container. The switch, which is located on the solar cell, can be switched to blue, orange or even ‘off’ for conserving more energy. Go get one – or two – or ten! They are great!

We thought we’d seen just about everything powered by solar panels or solar film until we came across this bikini. Made by Solarcoterie, this bathing suit is made of photovoltaic film strips sewn together in series with conductive thread! With a USB connection you could be laying on the beach and powering your iPod at the same time. The suit is constructed of 1″ x 4″ solar strips which terminate in a 5V regulator and a female USB connector – perfect for powering your iPod.

The down side is that the bathing suit is a currently custom made offering only so this is not something readily available at your local store. And, we don’t have the power specs but wonder if this also wouldn’t be a great solution for charging other small appliances needed at the beach – like most smartphones and iPads. Of course, this got us thinking about our dream ideas of powering a small cooler (imagine never needing ice at the beach!) or a small fan for cooling off while you’re baking in the sun. The biggest item on our wishlist is always a blender but we’ve got that covered with our battery operated one!

No matter what, we think this use of solar technology is genius.

Solar energy is an exciting field for both scientific study and home and office use, representing the modern drive to find clean, sustainable ways to power everyday life while protecting the planet for generations to come. Solar energy is created by the sun, which plays host to constant explosions of heat and energy. This energy radiates light that eventually reaches Earth, where water, land, and the clouds in the atmosphere absorb a portion.

This light manifests as heat and helps to regulate the planet’s water cycles, including rainfall. Solar energy is converted into food for trees and plants via photosynthesis, and in turn provides the Earth with oxygen and the natural materials necessary for human habitation.

With the many intrinsic and ancient benefits of solar energy we’ve enjoyed over the centuries, it is perhaps unsurprising that modern man has taken it upon himself to truly harness the potential of this natural power source. Solar power is fast becoming a popular way for businesses and homeowners to cut down on energy costs while making a commitment to the health of the environment.

Solar power itself can take many forms, operating for instance through the means of solar panels, which convert radiation from the sun to practical electric energy suitable for a variety of uses, and can store this energy in batteries.

Other common applications for solar power include pumps, switches, and fans for various industrial purposes, greenhouse and other thermal agricultural uses, and special technologies employed in space, such as those used to operate satellites.

Taking advantage of natural solar energy is not only an efficient way to power machines, houses, and more, but is cost-effective as well. Many entrepreneurs and environmentally savvy homeowners find that using solar power greatly diminishes their average monthly electricity expenditures, adding a welcome benefit to the clean and green energy source.

As oil prices fluctuate, and we become more aware of our impact on the global ecosystem, it is becoming imperative that we search for and use renewable sources of energy, and seek to live in a sustainable fashion, so that future generations can enjoy a happy and healthy planet. The use of solar energy through solar power panels and other technologies is an important step in reducing your overall energy footprint, and can give you — and your wallet — a sincere sense of peace and well being.

Yesterday, IKEA announced it had flipped the switch on newly installed dual rooftop solar units at its Tempe, Arizona store. The new system is one of the largest solar systems in the Phoenix area and the third such solar energy system for the Swedish home furnishings retailer; they have similar units already in place in Brooklyn, NY and Pittsburgh, PA.

The 300 kW solar energy system will generate 960,000 kWh of electricity annually from 2600 solar panels. It is the equivalent of reducing at least 760 tons of (C02) – which equals the emissions of 133 cars or powering 84 homes annually.

IKEA has other renewable energy initiatives in place. Already operating is solar water heating in stores in Charlotte, N.C.; Draper, Utah; Orlando, Florida; and Tampa, Florida. In addition, a geothermal system is being installed in a store under construction in Centennial, Colorado.

It was also announced that eight California locations are on deck for solar systems. In all, IKEA will be installing nearly 20,000 solar panels at eight of its California locations. IKEA expects the panels to generate 6.65 million kilowatt hours of electricity annually which is enough to power 580 homes for a year. Pending governmental approval, it will begin installing the renewable energy systems later this fall at existing stores in East Palo Alto, Emeryville, West Sacramento, Burbank, Costa Mesa, Covina and San Diego along with its large distribution center in Tejon.

With the installation of an array of 3000 solar panels, the New York Jets have really set themselves apart from other professional sports teams. Their team headquarters and 120,000 square foot training facility will be powered by the solar panels that will generate an estimated 750,000 kilo-watt hours of electricity.

Other sports teams have installed alternative energy systems at their training camps and stadiums, but the system at the Jets facility is the largest to date.

The New York Jets can wear their long-time green jerseys proudly – their commitment to providing a source of green energy at their training camp is an inspiration for the rest of the league.

As the popularity of solar energy grows, so does the selection of solar equipment that is made available. The big trend in solar energy right now is flexible panels.

Flexible solar panels have many advantages over traditional framed solar panels. The flexible solar panels are lightweight so there is less worry in the installation process and during use. They can also be installed on a semi-permanent basis because they are very easy to remove and install elsewhere.

Probably the biggest advantage is that they can be manufactured in any size or shape so they can be used in unconventional places.

In the past, the biggest disadvantage of the flexible solar panels is that they could only power low-wattage devices however that has changed significantly in the past year as new solar technology has been introduced. The newest flexible panels that are available for commercial applications have the ability to collect more energy than earlier versions.

In the future, we will be seeing even more advances in solar energy products based on this emerging technology.

Applied Materials announced this week that it was planning a major restructuring of it’s business. The goal? To place a “primary emphasis” on LEDS and crystalline silicon solar panel technology.

This restructuring would effect the bottom line of the company in many ways including the elimination of 400 – 500 jobs and the closing of their thin-film solar technology lab among other plans.

The future of Applied Material’s solar technology would focus on the crystalline silicon solar product development over the thin-film solar business. Historically, crystalline silicon (c-Si) has been used in many solar cells as a light-absorbing semiconductor although it is considered a relatively inefficient for light absorption. It also requires a considerable thickness (several hundred microns) of material.
Despite this, it has proven to be desirable because it produces stable solar cells with good efficiencies (11-16%, which is half to two-thirds of the theoretical maximum). It uses process technology developed from the huge knowledge base of the microelectronics industry.

Don’t you wish you could save some money heating your house? Here’s a super deal you won’t want to pass up.

If you’ve been waiting to start building a solar energy system, you’re in luck. We are offering our 50W Mono-Crystalline Solar Panels at a outrageously low price of $299.99. We only have 6 4 left, so don’t delay! We expect the 50W solar panels to sell out quickly at this price. We’re trying to get more, but we can not be sure we will be able to.

Multiple 50W Solar panels can be connected in series for more voltage, or in parallel for more current. Use these to in part to build complete on grid and off grid solar power generating systems. Excellent for use with deep cycle battery banks and solar charge controller regulator.

Added benefit: Our solar panels are made of Monocrystalline silicon. Mono-crystalline has been proven to be the best and most efficient raw material used in PV cells. Use Mono-Crystalline panels to capture the most energy from solar power.

Solar energy is a small investment that delivers big benefits. Once you are harnessing the power of the sun’s rays, you’ll wonder why you waited so long!

Growing demand for renewable energy sources has skyrocketed all over the world, but no where is this more evident than in China.

Take a look at the city of Rizhao where miles of dark tubing cover the roofs of apartment buildings and private homes. The reason? Using solar powered hot water heaters is mandatory in Rizhao. In fact, due to requirements such as this one, China has become the largest producer (and consumer of) solar hot-water heaters. Rizhao’s commitment to solar energy is deep: it has pledged to become the very first city in China to become carbon-neutral.

The good news for all of us is that the surge in solar panel requirements has created more supply, and thus lower pricing for all of us. The lower prices help make solar energy more affordable even here in the US.

As new panels are shipped to us, we will be passing on the new lowered prices to our customers. West Florida Components has just lowered our prices on all new solar panels by an average of 16%. Good news for all of us!
