How does cryptocurrency contribute to fossil fuel emissions?

Reading Time: 4 minutes

In February 2021, Tesla announced that it had purchased $1.5 billion in Bitcoin and planned to accept the cryptocurrency as payment, causing the price of Bitcoin to soar to record high numbers. However, three months later, Elon Musk disrupted the cryptocurrency market when he tweeted, “Tesla has suspended vehicle purchases using Bitcoin,” citing concerns about “rapidly increasing use of fossil fuels for Bitcoin mining and transactions, especially coal, which has the worst emissions of any fuel.” Overnight, the Bitcoin market dropped by almost 10 percent–so how founded are these environmental concerns in cryptocurrency mining, and could cryptocurrency have a clean energy future?

Is Panasonic exiting the solar panel industry?

Reading Time: 3 minutes

In February 2021, Panasonic announced that during fiscal year 2022 (ending in March 2022), it will stop producing photovoltaic (PV) modules (aka solar panels). This announcement created some confusion about Panasonic’s future role in the solar industry, causing some to wonder if the company will stop selling solar panels altogether. However, according to Panasonic’s press release, this is not the case! The company stated that it will “continue to sell outsourced photovoltaic modules as it has been doing in North America.” So the question is: how does this shift in production impact the company and its customers?

Tesla Solar Roof: the complete review

Reading Time: 9 minutes

In October 2019, Tesla Motors announced the launch of Tesla Solar Roof V3, the company’s third version of its integrated solar glass shingle. Among several updates, version three included larger tiles, lower production costs, increased power density, and an easier installation process. Additionally, the total number of parts in the product was decreased. Tesla predicted that these changes would significantly reduce the cost of the product; recently, however, the company has increased prices on previously quoted systems, without a lot of explanation.

Solar-assisted heat pump

What are solar-assisted heat pumps, and how do you compare them?

Reading Time: 4 minutes

According to the U.S. Energy Information Administration, space heating and water heating can account for almost two thirds of energy use in U.S. homes—those bills definitely add-up! You can use many different types of energy efficient heating systems to offset these costs, including solar-assisted heat pumps (SAHPs), which some manufacturers claim can have payback periods as low as two to three years. These systems combine technology similar to solar hot water and air source heat pumps in order to heat water or small spaces in your home. SAHPs have existed since the 1970s, but have recently started gaining more attention due to their high efficiency.

Agrivoltaics: what is it and can it benefit your farm?

Reading Time: 6 minutes

The farming industry has been hit hard by the impacts of climate change. From increasing temperatures to severe droughts, farms are facing new challenges that will likely increase with intensity as climate change progresses. Fortunately, a new solution is arising that can both benefit farmers and help reduce emissions: agrivoltaics (also known as dual-use solar).
