Halogen & LEDs

Halogen lamps are a type of incandescent, so the same restrictions apply to them. They can’t be recycled, so you can carefully dispose of them in your regular trash. Be sure to wrap them up so they won’t shatter! You can also try reusing them just like incandescents in various up-cycle craft projects.

Likewise, LED bulbs take a pretty long time to wear out, but eventually they will need to be replaced. LEDs don’t have mercury in them so they are safe to dispose in the normal trash, but depending on what your lamp looks like it might be great for crafts too! Anyone have a creative idea for LED recycling?

When it comes to residential electrical work, most people just call up an electrician without a second thought. And for good reason – working with electricity can be difficult and dangerous if not done properly. However, there are some simple jobs that amateur electricians can perform on their own if they have basic tools and experience. Read on for tips on how to run electrical wiring behind your walls without tearing up your home.

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.
