Green Your College Dorm Room
By Emily Deanne
Shower shoes? Check. Extra-long sheets? Yep. Energy efficiency checklist? No worries — we've got you covered there. If you're one of the nation's 12.1 million full-time undergraduate college students, you no doubt have a lot to keep in mind as you head off to school. If you're reading this, climate change is probably one of them, and with one-third of students choosing to live on campus, dorm life can have a big impact on the health of our planet. In fact, the annual energy use of one typical dormitory room can generate as much greenhouse gas pollution as the tailpipe emissions of a car driven more than 156,000 miles.
If just one in 10 students adopted energy-saving practices, we could avoid millions of pounds of climate-warming carbon pollution. Here are some ideas to help you do your part.
Conserve Heating and Cooling
Air-conditioning packs the biggest punch for dorm power usage, and if your room has individual temperature control, you can set it a few degrees higher to help cut back on how much energy the cooling system uses. Never leave a window open when an air conditioner (or heater) is running, and on hot, sunny days, keeping the blinds or curtains closed will block many of the sun's warming rays. In the winter, this will help keep the cold out, too. Year round, report broken windows, cracks in doorways, or any damaged thermostat controls to the university maintenance department.
Switch off your overhead light, desk lamp, and any other lights every time you leave the dorm. To take your environmentalism a step further, if the bulbs provided aren't LEDs, consider swapping some in. LEDs are 85 percent more efficient than old-fashioned incandescents and last much, much longer. If you decide to decorate with that dorm room staple, a string of holiday lights, make sure those are LEDs too. (Find tips on how to shop for energy-efficient bulbs here.)
The average dorm room consumes 30.2 percent of its electrical energy while you and your roomies aren't there, according to one study. That's because appliances continue to draw power from electrical outlets even when turned off or idle. A power strip or surge protector helps avoid this: You can plug all your appliances and devices into it, then easily stop them from drawing power with one switch.
Don’t Make Your Screens Work Too Hard
If you have a television, look for an energy-saving feature called Automatic Brightness Control. It automatically adjusts the picture brightness level to the amount of light in the room. Game consoles can be huge energy drainers if used to stream videos or if constantly left on. Instead, stream with apps already on your TV or with a streaming device (like Roku or Apple TV), which require one-fifteenth the energy. Keep the auto-power-down feature enabled so your game console doesn't consume power when you aren't using it.
Desk computers and laptops are college necessities, and as with your gaming console, you can typically program your computer to go into a low-power standby mode when you're taking a break. Look for an energy-saving or eco-mode.
Shopping for a new computer? Check out this website to find one that is certified by Energy Star to be energy efficient. (Any printer or mini-fridge you buy should be similarly certified.)
Reduce Water Use
If you have a dishwasher in your room or suite, run it only with a full load; the same goes for doing laundry. Wash clothes in cold water and consider using a drying rack instead of an electric clothes dryer, which often uses as much energy as a new refrigerator, dishwasher, and clothes washer combined.
If you live in an apartment-style dorm, more bonus points to you if you add a faucet aerator to your sinks. Aerators can reduce water flow to 1.5 gallons per minute or less from the standard flow of 2.2 gallons per minute. They are inexpensive and easy to screw onto the nozzle of your faucet, and they save energy by reducing your hot water use.
Save the Food
An NRDC study found that about 40 percent of food is wasted in the U.S., which leads to a lot of emissions from food rotting in landfills. (One such gas is methane, a greenhouse gas that is up to 80 times as effective at trapping heat as carbon dioxide). Do your part to help keep food scraps out of the landfill. Don't pile a tray with more food than you can possibly eat at the dining hall and keep a set of reusable containers on hand, in case you find yourself with extra slices from your late-night pizza delivery. With leftovers you can't store, it's best to toss them into a compost bin if there's one on-site or nearby; some cities host farmers markets where you can drop off composted food for free. You could even start a composting club or, if your roommate agrees, make your own composting worm bin.
Create a Movement
With communal spaces and shared amenities, it can be hard to regulate every part of your energy use. Talking with your resident advisor (RA) about ways to increase dorm energy efficiency is a great way to make meaningful change. You could also join—or even start—an environmental club or energy efficiency council on your campus. When you join together with other student activists standing up against climate change, your impact on greening college life will go well beyond those dorm room walls.

Winter is supposed to be the best season for wind power – the winds are stronger, and since air density increases as the temperature drops, more force is pushing on the blades. But winter also comes with a problem: freezing weather.

Ice buildup changes air flow around the turbine blade, which can slow it down. The top photos show ice forming after 10 minutes at different temperatures in the Wind Research Tunnel.

While traditional investment in the ocean technology sector has been tentative, growth in Israeli maritime innovations has been exponential in the last few years, and environmental concern has come to the forefront.
theDOCK aims to innovate the Israeli maritime sector. Pexels<p>The UN hopes that new investments in ocean science and technology will help turn the tide for the oceans. As such, this year kicked off the <a href="https://www.oceandecade.org/" target="_blank" rel="noopener noreferrer">United Nations Decade of Ocean Science for Sustainable Development (2021-2030)</a> to galvanize massive support for the blue economy.</p><p>According to the World Bank, the blue economy is the "sustainable use of ocean resources for economic growth, improved livelihoods, and jobs while preserving the health of ocean ecosystem," <a href="https://www.sciencedirect.com/science/article/pii/S0160412019338255#b0245" target="_blank" rel="noopener noreferrer">Science Direct</a> reported. It represents this new sector for investments and innovations that work in tandem with the oceans rather than in exploitation of them.</p><p>As recently as Aug. 2020, <a href="https://www.reutersevents.com/sustainability/esg-investors-slow-make-waves-25tn-ocean-economy" target="_blank" rel="noopener noreferrer">Reuters</a> noted that ESG Investors, those looking to invest in opportunities that have a positive impact in environmental, social and governance (ESG) issues, have been interested in "blue finance" but slow to invest.</p><p>"It is a hugely under-invested economic opportunity that is crucial to the way we have to address living on one planet," Simon Dent, director of blue investments at Mirova Natural Capital, told Reuters.</p><p>Even with slow investment, the blue economy is still expected to expand at twice the rate of the mainstream economy by 2030, Reuters reported. It already contributes $2.5tn a year in economic output, the report noted.</p><p>Current, upward <a href="https://www.ecowatch.com/-innovation-blue-economy-2646147405.html" target="_self">shifts in blue economy investments are being driven by innovation</a>, a trend the UN hopes will continue globally for the benefit of all oceans and people.</p><p>In Israel, this push has successfully translated into investment in and innovation of global ports, shipping, logistics and offshore sectors. The "Startup Nation," as Israel is often called, has seen its maritime tech ecosystem grow "significantly" in recent years and expects that growth to "accelerate dramatically," <a href="https://itrade.gov.il/belgium-english/how-israel-is-becoming-a-port-of-call-for-maritime-innovation/" target="_blank" rel="noopener noreferrer">iTrade</a> reported.</p><p>Driving this wave of momentum has been rising Israeli venture capital hub <a href="https://www.thedockinnovation.com/" target="_blank" rel="noopener noreferrer">theDOCK</a>. Founded by Israeli Navy veterans in 2017, theDOCK works with early-stage companies in the maritime space to bring their solutions to market. The hub's pioneering efforts ignited Israel's maritime technology sector, and now, with their new fund, theDOCK is motivating these high-tech solutions to also address ESG criteria.</p><p>"While ESG has always been on theDOCK's agenda, this theme has become even more of a priority," Nir Gartzman, theDOCK's managing partner, told EcoWatch. "80 percent of the startups in our portfolio (for theDOCK's Navigator II fund) will have a primary or secondary contribution to environmental, social and governance (ESG) criteria."</p><p>In a company presentation, theDOCK called contribution to the ESG agenda a "hot discussion topic" for traditional players in the space and their boards, many of whom are looking to adopt new technologies with a positive impact on the planet. The focus is on reducing carbon emissions and protecting the environment, the presentation outlines. As such, theDOCK also explicitly screens candidate investments by ESG criteria as well.</p><p>Within the maritime space, environmental innovations could include measures like increased fuel and energy efficiency, better monitoring of potential pollution sources, improved waste and air emissions management and processing of marine debris/trash into reusable materials, theDOCK's presentation noted.</p>
theDOCK team includes (left to right) Michal Hendel-Sufa, Head of Alliances, Noa Schuman, CMO, Nir Gartzman, Co-Founder & Managing Partner, and Hannan Carmeli, Co-Founder & Managing Partner. Dudu Koren<p>theDOCK's own portfolio includes companies like Orca AI, which uses an intelligent collision avoidance system to reduce the probability of oil or fuel spills, AiDock, which eliminates the use of paper by automating the customs clearance process, and DockTech, which uses depth "crowdsourcing" data to map riverbeds in real-time and optimize cargo loading, thereby reducing trips and fuel usage while also avoiding groundings.</p><p>"Oceans are a big opportunity primarily because they are just that – big!" theDOCK's Chief Marketing Officer Noa Schuman summarized. "As such, the magnitude of their criticality to the global ecosystem, the magnitude of pollution risk and the steps needed to overcome those challenges – are all huge."</p><p>There is hope that this wave of interest and investment in environmentally-positive maritime technologies will accelerate the blue economy and ESG investing even further, in Israel and beyond.</p>
