Thomas Edison once said, "I'd put my money on the sun and solar energy. What a source of power!"
Over the last ten years, solar power has become ubiquitous in conversations about renewable energy. As the cost to produce solar photovoltaic cells has plummeted in recent years, more and more homes, businesses and communities have invested in solar.
Solar has become a foundational renewable energy source, with major investments driving new project development all over the country. As the technology continues to develop, the future of solar is an even more exciting place to look.
The First Rays of Progress
The year was 1839. At just 19 years of age, French Physicist Edmond Becquere created the world's first photovoltaic cell. His discovery, known as the Photovoltaic Effect or "Becquerel Effect," showcased the foundational physics and process for what we now consider solar power and cemented his place in the history books. However, his discovery did not kick off a solar revolution. Instead, it remained in the domain of the laboratory well into the 20th century.
In 1954, inventors David Chapin, Calvin Fuller and Gerald Pearson capitalized on the Becquerel Effect, creating the world's first modern solar cell at Bell Labs. The very next year Hoffman Electrics produced their own solar cells, which sold commercially for 25¢ each. As solar technology continued to develop, solar power expanded to cars, planes, satellites, homes, commercial buildings and even spacecraft.
Over time, the basic concept behind solar hasn't strayed far from early models. However, the cells used to power our homes and lives today are much, much more advanced and efficient — driving down costs and opening up new uses for solar in our lives.
The Current State of Solar Technology
The solar industry has expanded and matured in recent years, accompanied by advances in power storage, miniaturization and materials that combine to make solar photovoltaics more efficient and durable and versatile.
In a sure sign of industry maturity, some companies are beginning to focus on the aesthetics of solar systems, instead of concerning themselves solely with advances in performance. One such company is Sistine Solar, a Boston-based startup which has created a "solar skin" that covers solar panels, altering their appearance. From skins that match the roof to artistic flags and designs, these skins help homeowners blend or beautify their rooftop panels without affecting efficiency.
That said, scientists and developers continue to push the limits of panel efficiency. The more efficient a panel is, the more energy created, and cheaper these panels can be in the long term. Most solar panels fall in the 14 to 18 percent efficiency range, but in 2018 a number of companies brought panels to market in the 24 to 25% range.
The current state of solar technology is promising, but it pales in comparison to what the future holds.
A Limitless Solar Future — If We Can Build It
Solar's potential seems limitless, but it would be wrong to consider the matter settled. Despite the astounding pace of innovation, solar technologies have only effectively doubled since the first cell was created in 1954. Furthermore, humankind's demand for reliable power shows no signs of slowing. In order to fully utilize clean, renewable solar energy, scientists, policymakers and financiers the world over are going to have to be clever.
Looking ahead, some researchers and thinkers asked: how could we offer solar energy round the clock, while maintaining the ability to meet increasing energy demand. The answer, it seems, is to create solar farms in space.
The idea of launching solar panels into space where they can generate electricity 24 hours a day and wirelessly transmit the power back to Earth might seem like science fiction, but it's becoming increasingly more likely by the day.
As a concept, wireless transmission of energy has been with us since the invention of the radio, and the first notable long distance power transmission experiments occurred in 1982. In 2018, scientists from the California Institute of Technology announced that they had succeeded in creating a prototype of a lightweight tile which would be capable of harnessing and transmitting solar energy generated from space. These lightweight tiles would have the ability to follow the Earth's orbit, meaning power would flow continuously, without a night time dip.
While orbital solar farms might still lie in the future, terrestrial solar is a very real presence in our lives today. As solar power continues to enjoy advances in technology, performance and cost efficiency, solar looks poised to be one of our most prevalent sources of clean, renewable energy. Not just in our power supply, but in our tech, toys and daily lives. Without a doubt, solar will be one of the pillars of our 100% clean energy future.

Jean-Marc Neveu and Olivier Civil never expected to find themselves battling against disposable mask pollution.
When they founded their recycling start-up Plaxtil in 2017, it was textile waste they set their sights on. The project developed a process that turned fabrics into a new recyclable material they describe as "ecological plastic."
Mounting Piles of Waste<p>It is not only the streets of Chatellerault where pandemic pollution is piling-up, but also the world's beaches and oceans. Once there, they can take up to 450 years to degrade and disappear.</p><p>Esther Röling, co-organizer of the annual Adventure Clean Up Challenge held on Hong Kong Island, has seen this waste firsthand. In October the sports challenge pitted teams against one another in a competition to remove trash from 13 hard-to-reach coastal areas around the city.</p><p>They find tons of both disposable and reusable masks, said Röling. "You wonder how it ended up there. Was it just thrown on the ground? Or was it in a garbage bag that broke open?"</p><p>Almost 10,000 kilometers away in Antibes on the sunny French Riviera, it's a similar picture. For the past few months, divers and clean-up volunteers working with an ocean clean-up non-profit called Operation Mer Propre have been collecting an increasing number of masks found on land and in the sea.</p><p>"Since the beginning of the lockdown when we started to count, we've reached 800, 900, [and now in total] 1000 masks," said co-founder Joko Peltier. </p><p>According to <a href="https://unctad.org/news/growing-plastic-pollution-wake-covid-19-how-trade-policy-can-help" target="_blank">UN estimates</a>, up to 75% of all coronavirus-related plastic could end up as waste in oceans and landfills.</p>
The Limits of Recycling<p>Yet not all are convinced the recycling of this waste is possible on a global scale. </p><p>"What those citizen groups are doing is really beneficial but once they collect it, it should just go to a landfill or an incinerator. They shouldn't necessarily expect it to get recycled," said Jonathan Krones, an industrial ecologist and visiting assistant professor of environmental studies at Boston College.</p><p>That's because mask recycling programs like Plaxtil are few and far between and most don't have the benefit of a readily adaptable production process. </p><p>Even in countries with solid recycling infrastructure, he says, the system is designed to separate out specific types of waste like bottles or cardboard.</p><p>"I imagine that it would be technically feasible to develop a separation process to filter out masks, but there simply aren't enough of them to make that economical," he said.</p><p>Collection is a big hurdle, he adds. Since each mask only weighs a fraction of a gram and they're scattered on roads or mixed with other trash, it is difficult and costly. </p><p>"You need a lot of raw material of the right quality to make investing in the recycling technology and the recycling system worthwhile," he said.<span></span><br></p>
Hemp, Sugar Cane and Sustainable Alternatives<p>Some projects are instead addressing the material used to make masks.</p><p>French company Geochanvre have created a mask made primarily from hemp, while in Australia, researchers at the Queensland University of Technology are experimenting with a disposable product made from agricultural waste. </p><p>Biodegradable options are exciting alternatives to reduce the fossil fuels needed for the creation of plastic-based masks, said Krones, but they don't absolve the wearer from the responsibility of what happens afterwards. </p><p>Bio-based masks often need their own composing solutions, he explains, because in landfill they can produce high amounts of the greenhouse gas methane when anaerobic bacteria feeds on the organic material. Methane is known to be significantly more potent than carbon dioxide.</p><p>"I think as long as we have in our mind that we want to have disposability, we're going to have to wrestle with a variety of different sorts of environmental tradeoffs," he said, adding that reusable, fabric masks are the best option available to most people.</p><p>Precimask is developing a clear face covering with an optional visor made from hard plastic, designed to be long-lasting.<br></p><p>Air enters either side of the cheeks through a technology normally found in pool filters and car exhaust systems, said company spokeswoman Juliette Chambet.</p><p>"We wanted to make ceramic-based filters that would be washable and cleanable, which would allow them to be reused as many times as desired without having to buy a new consumable or produce waste," she said. </p><p>Ultimately, encouraging mask wearers to think about the entire lifecycle of a mask is key, explains Neveu. </p><p>"We want people who put on the masks to realize that they are also responsible for the waste, he said. "It's not inevitable that this [pandemic] will become an environmental catastrophe.</p><p><em>Reposted with permission from </em><em><a href="https://www.dw.com/en/covid-19-recycling-pollution-trash-pandemic/a-55707817" target="_blank">Deutsche Welle</a>.</em><a href="https://www.ecowatch.com/r/entryeditor/2649032193#/" target="_self"></a></p>
