Photovoltaics employ solar panels to create energy. Solar power remains a rapidly growing field in the renewable energy sector. It has the potential to completely power our world and drastically reduce greenhouse gas emissions.

Aside from large-scale solar plants, photovoltaics can also be found in a variety of places from calculators and watches to electric planes and the space station. The lack of moving parts makes them valuable in portable devices and in areas without other sources of power. And because the only source of fuel required is sunlight, they can produce power continuously for years without maintenance. Thanks to the falling cost of installation and the potential savings on utility bills, many homeowners are now choosing to install rooftop panels on their own homes.

As the cost per watt of solar power continues to plummet, new solar technologies are emerging. Therefore, the second generation of solar panels, known as thin-film PV, consist of extremely thin panels only a few micrometers thick. These panels are much more versatile and have found their way into Tesla’s solar roof tiles, among other things. They are less efficient than first-generation panels, but much cheaper, simply due to the fact that they require less material to manufacture.

Most noteworthy, third-generation high-intensity solar cells are also in development and promise to be even thinner and extremely efficient. Perovskite PV cells and Organic and Polymer Photovoltaic (OPV) cells are some of the newest third generation solar technologies and use materials other than crystalline silicon.

Photovoltaics remains a quickly growing field that has the potential to reduce greenhouse gas emissions. This technology provides energy independence, while powering the world reliably and efficiently.

When it comes to creating stunning interior spaces in their homes, property owners pull out all the stops. They hire the best designers, choose the best materials and hire the best contractors for all the installations. While all these aspects are important, it’s also important to have the right kind of lighting. After all, you do want your home to look as stunning after dark, as it does during the day, don’t you?

However good lighting is never a matter of chance. It takes a great deal of planning and choosing the right fixtures and lighting systems and bulbs to ensure you are able to achieve the effect you want. Lighting has the potential to completely transform the look of your home and it can turn your house into a welcoming and comfortable home.

Regardless of how well thought-out all the other details in your décor and interior design are; all your luxurious flooring, stunning wall coverings and superb furnishing won’t have the right impact if your lighting isn’t planned well. Here are some aspects you should consider while lighting any residential space:

Every room will need a different type of lighting; and this will be dependent on the activities that take place in that room. Here are some pointers:

If your home has high ceilings, you can use recessed lighting- these fixtures are inserted into ceilings and the fixture is fitted inside it. Adding dimmer switches to these directional lights allows you the flexibility to change the lighting effect from subtle to full-bright.

It’s a good idea to add this in most rooms; it’s especially important that you have night lighting incorporated into kid’s rooms and nurseries. Table lamps and wall sconces are a good option for these spaces.

Many people like to have chandeliers in these rooms. Choose these smartly and ensure that the one you opt for doesn’t date the space. If you have very elaborate and embellished interiors, a traditional, opulent chandelier might look stunning, but it will look completely out-of-place in a modern-styled home.

For the latter, you should opt for more minimalistic chandeliers that have simple designs with small and ornate crystals to throw more light. No matter what type of décor you have, it’s important that you measure-out the entire space as well as the ceiling height in every room before you order pendant lights or chandeliers, and ensure there’s sufficient head room under these fixtures.

If the department stores are to be believed, the holiday season started about a month ago—which means if your house isn’t already fully decorated, you’re way behind! This year, make sure your holiday lights are safe by following these tips:

Before you buy or install new lights, make sure you know both how many watts the decorations require and how many watts are available in your home (if you’re not sure, ask an electrician at Kolb Electric!). Remember—the lower the wattage, the less electricity your lights will consume and the less they will cost to operate.

Since holiday lights draw so much power, you probably don’t want to plug them into a circuit that you’re using for other appliances—the circuit is likely to blow. Instead, call a DC electrician to install a dedicated circuit for your decorations.

In addition to installing a dedicated circuit for your holiday lighting, you may also want to install a timer for your lights. A timer will shut off your lights automatically, adding security and making sure everything is off in the middle of the night.

Extension cords are susceptible to water damage, so if you plan to use any outside, make sure they are covered so they can’t get wet. Never connect more than three strings of lights either—if you need more length, use a different plug.

Above all, make sure you take ordinary precautions with your holiday lights. This includes:

At Kolb Electric, we want to wish everyone a happy and safe holiday season. And if you need electrical service in Washington, DC, Maryland, or Virginia, call Kolb Electric today!

Last night, thousands of walkers and hundreds of runners in Edinburgh kicked off the Courtesy of NVA.org.uk

A bunch of research went in to creating this light up gear to meet the NVA’s head designer James Johnson’s following standards:

For the runners, the design team wanted something dramatic, so they ended up going with concentrated point source LEDs, which looked great both close and at a distance. The LEDs allowed them to mix color and adjust intensity of the lights remotely. The runners themselves had to be in tip-top shape, able to run 10 miles at a 9-10 minute pace in all kinds of weather. Therefore, as to not hinder them in their physical feat, the design team fashioned a webbing suit out of the LEDs, complete with a radio and battery pack. Check them out:

The only shortcoming of these suits was that they couldn’t be powered by the runner’s motion. After attempting to harvest energy via knee braces, they determined any impediment to the runner’s motion dramatically affects his or her performance.

For the walkers, Johnson and his team wanted to build something subtler, to provide adequate safety lighting, but not to distract from the viewing experience. They decided to go with staffs/walking sticks illuminated by a combination of electroluminescent tape, fiber optic fabric, and diffused and non-diffused LEDs. Each staff housed a micro-computer that would synch up the flashing patterns with the Orchestra’s score, with changes triggered by movement and altitude. And here they are:

The research team was able to use motion to generate power in this instance, since walking is a more leisurely, steadier movement. To harness the power of movement, two LEDs, two high power Neodymium magnets, and a copper coil go in the top of the staff, then as the walker strides along, striking the stick against the ground, one of the magnets oscillates through the coil, creating a small electrical current. One LED lights up when the magnet travels down, and the other when the magnet travels up, producing a twinkly effect.

The runners also received a smaller version of this staff in the form of a baton.

Spring weather is finally here, a welcome relief for those parts of the country that have spent the last few months plagued by snow and ice. With the warm weather comes an increased dependence on air conditioners, which can use up a large amount of energy and add to your utility bills each month. There are certain steps you can take to reduce the overall electrical consumption of your house so you do not have to pay as much when you write out that check.

Here are a few ways you can improve your home's power use:
