GRAND JUNCTION, Colo. (KREX) – At this week’s Energy Summit hosted by the Grand Chamber of Commerce, expert speakers were given the opportunity to share information on topics such as the future of solar energy with local residents.

The Energy Summit examines the use of geothermal energy

One of the speakers, Matt Fowler of the Atlasta Solar Center, had the opportunity to share his thoughts on the solar panel industry and its future on the Western Slope. Introducing Grand Valley locals, Fowler noted that solar panels continue to have a negative stigma around them in terms of price.

But in the end, Fowler says, customers are saving money, and prices have dropped significantly over the past decade. KREX will continue to monitor the future of solar energy on the western slope.

Renewable energy sources – especially solar and wind power – now dominate new US power plants. However, they do not dominate the production of electricity in the country.

December 2021 Renewable Energy Production

In December 2021, renewable energy sources in the United States accounted for 23.8% of electricity generation. Wind energy alone was 11.9% and solar energy 2.7%.

The good news is that this is especially high from December 2019 and December 2020. In December 2019, these figures were 17.5% of renewable energy, 7.8% of wind energy and 1.6% of solar energy. In December 2020, they improved to 19.4%, 9.2% and 2.2%, respectively. Thus, you can see that all new solar and wind power leads to a significant increase in electricity generation from renewable sources. Simply put, the network is so large and power plants are so long-lived that even 100% of the new energy capacity from renewable power plants means a slight increase in the share of renewable energy in electricity supply.

In December 2019 and December 2020, both nuclear and coal generated more electricity than renewable energy sources. In December 2021, renewable energy sources surpassed both of them and gained strong leadership – 23.8% of electricity from nuclear power plants, 20.6% from coal-fired power plants and 17.5% from coal-fired power plants.

Interestingly, hydropower (part of the renewable energy supply) also saw a leap in production during that period. It rose from 6.3% in December 2019 and 6.2% in December 2020 to 7.5% in December 2021.

Now let’s look at full annual comparisons.

2021 Renewable Energy Production

It’s a similar story for the whole year, but the numbers aren’t as good as they were in December – maybe it’s a sign that the story continues to improve from month to month, or it’s just due to changes in the seasons and winter. a great month for wind energy.

Renewable sources accounted for 21% of electricity in the United States in 2021, up from 18.3% in 2019 and 20.3% in 2020.

The sun and wind make up the majority of this cake, accounting for 13% of all U.S. electricity production in 2021, up from 9.7% in 2019 and 11.6% in 2020.

Renewable energy sources have already reached the point of intersection with coal and nuclear power in 2020, but the bad news is that renewable energy sources fell slightly below coal levels again in 2020 – from 21% to 21.6%.

Why is solar energy bad for the environment? Solar panels are made up of photovoltaic (PV) cells that convert sunlight into electricity. When these panels enter landfills, valuable resources go to waste. And because solar panels contain toxic materials such as lead that can be released as they break down, landfilling also poses new environmental hazards.

Are solar panels actually bad for the environment?

But the toxic nature of solar panels makes their environmental impacts worse than just the amount of waste. Solar panels are delicate and easily broken. In doing so, they instantly become dangerous, and classified as such, due to their heavy metal content. Therefore, they are classified as hazardous waste.

Is it profitable to recycle solar panels?

Researchers ’projections showed that 40% of all solar panels could be reused and recycled using subsidies equal to $ 18 per panel for 12 years. With that price, a profitable and sustainable solar panel recycling industry can establish itself by 2032.
