Halloween is less than one month away! If you’re thinking of decorating your home for the holiday, nothing can help turn your house into a festive sight like lighting. In minutes, you can turn your quaint cottage a ghoulish green, make your bungalow glow orange, or paint your front lawn an eerie yellow. Suddenly, your charming home becomes mysterious and thrilling to trick-or-treaters and passersby.

Light dimmer switches are now common in most modern homes. Lighting affects the mood and comfort level of any given room. A bright halogen lamp just doesn’t help you wind down after a long day’s work, and a candle doesn’t work when you’re trying to make dinner. Dimmers can solve this problem.

If you use your dimmer often, however, you may notice it getting hot. Understandably, this can be disconcerting to a homeowner. If a dimmer gets too hot, it can actually melt the plastic plate or degrade  the electronic components.

Reasons for a Warm Dimmer

Basically, modern dimmers use a triac—a semiconductor—which works like a transistor. This allows the dimmer to control the amount of electricity going to your lights. This also means, however, that there will be a buildup of heat, which needs to be dissipated. A metal mounting plate is generally where the heat is distributed and then dissipated through the switch plate cover..

If your dimmer is running a single 100-watt bulb, you probably won’t notice any excess heat. However, if the wattage being controlled is in excess of  300 watts or more, you may start having issues. It’s not dangerous to run wattage that high (or higher), but you need to be using a system that is rated for that wattage, which is often not the case.

Dimmer ratings apply if the dimmer is mounted in a single gang box – meaning it is mounted alone.  If a dimmer is mounted in a box with other switches or dimmers, some of the heat fins must be removed resulting in a de- rating of its current carrying capability.

What You Can Do

First, you want to see if your dimmer switch is rated high enough for the amount of lighting it is running. You could also try using lower-wattage bulbs to reduce the overall amount of heat going through the switch.

In some cases, the actual casing and/or trim plate could be the culprit. Today, most electrical boxes are plastic, but metal is a much better conductor of heat. Changing from a plastic to a metal box will help, as well as replacing a plastic trim plate with a slightly larger metal one.

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.
