Waste Heat Recovery

Does your laptop ever get extremely hot and start to make loud noises as if it’s going to explode? That’s because when we use our devices for too long, it can cause them to overheat and make the problems worse.

This is where waste heat recovery comes to the rescue. Waste heat recovery collects unwanted heat from a product and turns it into energy that can be used elsewhere.

There are many common household appliances that produce waste heat. Dryers, fire heaters, and steam boilers, to name a few. Waste heat recovery reduces the heat from these appliances so they don’t overwork themselves and break down.

According to the U.S. Department of Energy, 50% of energy from burned fuels in the U.S. become waste heat in the atmosphere. With waste heat recovery, we could attain 20% of total domestic electricity demands and reduce greenhouse gas emissions.

Photovoltaic Energy

Over the last few weeks we’ve discussed some of the most popular sources of renewable energy: Wind and Hydro. 

Solar power, specifically photovoltaic power, has been key to clean energy in the last 30 years. These thin material systems rank 3rd in global energy capacity, and will continue to contribute in growing renewable efforts.

Rise to Power

Photovoltaic energy is extracted from semiconductors that convert energy from UV rays into electricity. These devices, often referred to as PV devices, can power anything from a cell phone to large businesses.

Alexandre Edmund Becquerel introduced the idea of photovoltaic energy in the 1800s. Increased experimentation carried well into the 20th century and evolved into a viable energy source by the 50s.

Falling only third behind wind and hydro, PV energy is predicted to become the most widely used source of alternative electricity. Since the 90s, photovoltaic systems have been used in small applications. In 2000, Germany piloted its first mass market project roofing 1,000 homes in photovoltaic devices.

Over time, production and installation prices have fallen significantly, making PV systems more attainable to home and business owners alike. Though PV devices only account for less than 5% of global energy sources, considerable growth is imminent.

Modern Applications

From new innovations to real-life implementation, photovoltaic systems are leading the way in renewable energy. As this type of solar power grows in mass production, scientists are actively searching for ways to create more effective and inexpensive devices.

Here are some of the latest advancements.

Thin Film Materials

The most popular PV system is a thin film model that’s relatively cheaper to produce. Silicon based materials have dominated the market and experiments for years. Its cost effective appeal has made it a popular choice for larger operations.

A team of physicists at the University of Buffalo recently created a new thin film made of nontoxic barium zirconium sulfide. It's just as cost effective but has a greater energy output potential. This discovery has introduced new possibilities for semiconductor materials and a new wave of PV devices.

Power in Transparency

In 2012, researchers at UCLA developed a double layer photovoltaic device intended for windows, sunroofs, etc. This model was made of crystalline silicon and wasn’t fully transparent, boasting a reddish hue. While not completely practical for its intended applications, it paved the way for further advancements. 

In 2019, scientists in Korea modified this experiment by adding perfectly placed holes in the film creating a “transparent” appearance to the naked eye. This model still possessed a slight coloration, but was significantly less than the original material.

Mass Production

Currently, renewable power accounts for almost 45% of Brazil’s primary power. The country uses hydropower to supply approximately 80% of its electricity, and intends to use PV plants to fill the gap.

Brazil’s Sao Goncalo solar PV plant holds the largest photovoltaic system in South America, generating more than 1,200 gigawatts per hour. The system has been running since early 2020, and gives promise to those looking for sustainable energy at large.

Low cost materials and reasonable installation prices make PV systems an ideal technology for renewable energy. Photovoltaic energy will be the growth driver in global renewable energy in the years to come.

A New Wave of Clean Energy

clean energy from the ocean

It’s easy to imagine sun and wind energy. We’ve seen the solar panelling on rooftops and wind turbines in vast fields. Yet, what happens when there’s not enough sunshine or wind to generate power? Those energy sources become obsolete, and people resort to traditional methods.

We’re not saying these aren’t solid energy sources, but they do have limitations hinged upon weather patterns and eco systems.

Ocean energy harvesting is bringing a new wave of renewable power. Pun intended.
