When a wind turbine performance upgrade isn’t what it seems

| July 30, 2019

Over the past year, many of our customers have been approached by wind turbine manufacturers offering upgrade packages. Many upgrades are software updates, and some include hardware such as Vortex generators, which are attached to wind turbine blades and aim to improve the power, loads and the service life of a wind turbine. These upgrades can have a positive uplift on energy yield and we have seen the claims of 1-2% annual energy uplift can be achieved for some types of upgrades.

How the solar industry can deal with supply chain interruptions during COVID-19

Article | April 1, 2020

With the onslaught of the worldwide COVID-19 pandemic, we are all experiencing an unprecedented time. As the global economy wrestles with defining which industries and businesses are essential and non-essential, the United States has determined that construction, manufacturing and energy are essential businesses. Many companies and jobs within the solar industry fall into construction, manufacturing or energy, and in some cases all three categories. At Quest Renewables, we have outlined how we can limit interruptions to our supply chain during the current atmosphere. Our hope is that you will find this information helpful.

The Next Renewable Energy Source Could Be Rain

Article | February 17, 2020

The quest for the next source of renewable energy is well underway, with no natural phenomenon overlooked. We have already harnessed the power of flowing water, wind, and sunlight, and the search for the next clean source of energy is far from over. The latest potential breakthrough in renewable energy comes in the form of rain. The rain has not been getting a lot of attention in renewable energy circles perhaps because it would be challenging to harness its electricity-producing potential. Yet attempts are being made, and in the latest breakthrough, U.S. and Hong Kong researchers have managed to produce 140 volts of power from one single raindrop. That’s enough to light 100 LED lights for a short while.

What It Really Means When Google and Apple Say They Run on 100% Renewable Energy

Article | April 8, 2020

Apple, Amazon, Google, Facebook, and Microsoft — the five companies that arguably make up “big tech” — say they are either already powered by 100% renewable energy or are close to getting there. Together these companies own and operate more than a hundred data centers (each the size of multiple football fields), close to a thousand offices, and countless other buildings, making them some of the most power-hungry companies in the world. Given this, running on 100% renewable energy is a significant achievement. But there are plenty of critics who argue that these claims are misleading. Some say carbon offsets might do more to assuage guilt than they do to help the environment. To understand where these arguments come from, let’s start with the basics.

Recognizing and solving challenges in renewable energy land usage

Article | February 14, 2020

As anyone familiar with the saga of the Spotsylvania solar project knows, an inherent difficulty in developing renewable energy projects comes in finding the right project location, both in terms of size and siting. This is one of the topics analyzed in a new report released by The Brookings Institute: “Renewables, land use, and local opposition in the United States.” It’s a hard fact that renewable generation uses more land than fossil fuel systems, with solar having slightly lower median land use than both on- and offshore-wind, despite a large variance in total land density values. While this presents an issue for renewable developers, the silver lining is that renewable energy can be sustained indefinitely on the same land base, while mines and wells will eventually run out. As a solution, the study recommends greater development on brownfields, as well as floating PV, though the authors do recognize the capped potential of floating PV at around 10% of current U.S. electricity generation.
