LG & Sense

Breaking down the LG Solar and Sense partnership

Reading Time: 4 minutes

In May 2021, LG Solar and Sense announced their new partnership with the goal of empowering homeowners to make smarter energy decisions. LG has long been a household name due to their high-quality electronics and their subsidiary, LG Solar, has been no different. LG Solar is a leading manufacturer of solar panels with two residential series: the NeON 2 and the NeON R. 

Sense entered the energy space in 2016 with the launch of their Home Energy Monitor. Their energy monitoring system provides you with insights about your energy usage, allowing you to make informed decisions about what devices you’re powering and when you’re powering them. We sat down with LG Solar to learn a bit more about their new partnership, and its potential benefits.

What are the best solar batteries available? Top brands and products of 2021 compared

Reading Time: 8 minutes

Storage systems are becoming increasingly attractive home upgrades for homeowners across the country. Whether you’re looking for self-consumption, rate arbitrage during peak hours, or back-up power in case of emergencies, storage systems can provide greater independence, resiliency, and savings–especially if you have solar panels and live in a state without net metering

Because storage systems have become so popular, many companies are now in the market, making it more challenging to compare and decide between the different brands and products available. In this article, we’ll explain some of the most important factors for comparing solar batteries and we’ll discuss some of the best brands and products available now.

Cybersecurity: why it’s important for your solar panel system

Reading Time: 5 minutes

In May 2021, the cyberattack on the Colonial Pipeline made headlines across the country. After Colonial shut down their pipelines, gasoline shortages rapidly drove up the price of gasoline and spurred panic buying at fuel stations, particularly across hard-hit southern states. With cyberattacks on energy infrastructure increasing in frequency and severity, many are starting to wonder: what else could be at risk?

Unfortunately, the energy sector has already seen serious cyberattacks in the past–which could be an indicator of future risk. In 2015, Ukraine experienced the first known cyberattack on the power grid, which caused outages at 30 substations throughout the country and left about 230,000 people without electricity for up to six hours. People with solar-plus-storage systems would typically have the benefit of grid resiliency in such a situation and would be able to keep the power running–however, solar systems are not entirely immune to the risk of cyberattacks without proper protections.

Lithium mining in the United States: why is it so controversial?

Reading Time: 4 minutes

Lithium, the lightest element of all the metals, is a crucial resource for the United States’ clean energy future: it’s key in the production of lithium ion rechargeable batteries, which are used to power electric vehicles and serve as home storage systems. While the U.S. is the largest consumer of lithium and will only increase its future consumption as it strives to meet the Biden Administration’s ambitious greenhouse gas emission targets, America’ domestic mining of lithium is limited to just one percent of annual global production.

Currently, only one lithium mine operates in the United States, the Silver Peak mine in Clayton Valley, Nevada; most of the global lithium supply is extracted in Chile and Australia. While some politicians are calling for increased domestic mining of the metal, at the end of May 2021, Reuters reported that the Biden Administration would supply the majority of lithium from ally countries, including Canada, Australia, and Brazil. Though this strategy may seem antithetical to the Administration’s clean energy jobs goals, it comes on the heels of many environmentalists’ concerns over two potential lithium mines in Nevada that could become operational in a few years. In this article, we’ll break down lithium mining and why these two mines are so controversial.

The Ford F-150 Lightning: what you need to know

Reading Time: 5 minutes

For the past 39 years, the iconic Ford F-Series, which primarily includes the F-150, has been the best selling vehicle in the United States, selling just shy of a million vehicles in 2020. As automakers across the U.S. race to electrify their fleets, there’s been one major gap in announcements of new electric vehicles: what would happen with America’s best selling car? In May 2021, Ford put an end to that speculation, launching the new Ford F-150 Lightning. 

While the Lightning won’t be the first electric pick-up truck in the U.S., it may be the most important one. It’s not only a stronger, faster version of the trusted F-150, but by being completely electric, the F-150 Lighting comes with additional features that could attract both new and former F-150 customers. In its first 48 hours of accepting reservations, Ford had almost 45,000 reservations; after a week, this number increased to 70,000. The truck officially goes on sale in 2022.

Thermodynamic Solar Panels

Thermodynamic solar panels: what are they and how do they work?

Reading Time: 3 minutes

Typically, when you think about solar panels, you picture solar photovoltaics (PV): panels that are installed atop your roof or in an open space and convert sunlight into electricity. However, solar panels can also be thermal, meaning that they convert sunlight into heat as opposed to electricity. Thermodynamic solar panels are one type of thermal solar panel–also called a collector–that differ dramatically from traditional thermal panels; instead of requiring direct sunlight, thermodynamic solar panels can also generate power from heat in the air.

Solar Supply Chain

How are supply constraints impacting the solar industry?

Reading Time: 5 minutes

While many COVID-19 pandemic restrictions are starting to be lifted across the United States, pandemic-related supply chain issues continue to be felt across many sectors, including the solar industry. In spring 2020, solar equipment manufacturers experienced significant delays due to workplace and travel restrictions. As the pandemic continued throughout 2020 and into 2021, consumer demand largely shifted away from services, such as dining and travel, towards goods, such as computers and televisions, leading to shortages for key manufacturing components. In this article, we’ll cover some of the supply constraints currently facing the solar industry, and how these constraints are impacting solar shoppers.

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?
