Caribbean beaches are ankle-deep in slimy, smelly seaweed. Wave after wave of sargassum is blanketing shorelines from Barbados to Cancún. It traps sea turtles. It smothers coral reefs. And it drives tourists away from islands that depend on them. This seaweed isn’t just crashing weddings on the beach. It’
With the recent news of China producing one of the largest wind turbines yet, with a rotor diameter of 260 meters (853 feet) and a rating of 18MW, it got me wondering why they’re so big. They’re almost defying imagination at this point. Bigger is always better in
The vast majority of the world’s plastic isn’t recycled … and when it is, we spend more money to achieve less quality. It’s currently cheaper to keep producing newer plastics — at the much higher cost of human and environmental health. But nature has evolved in response. Several species
As our needs for energy and food continue to rise, we’re revisiting the sunny topic of Agrivoltaics – or using land to grow food and host solar panels at the same time. Experiments in this hot space have had some really promising results over the last year, like using new
To live, people need food to eat and water to drink. That’s a simple fact. But with growing water scarcity around the world and an ever increasing population, we have to find better ways to produce the food we all need to survive. The solution could lie in one
Heat pumps are versatile, efficient, and great for both heating and cooling … or are they? Whenever heat pumps are mentioned, critics bring up their ineffectiveness in the cold, so is that still true? Or do more modern heat pumps continue to work effectively in cold climates? I’m currently building
With the ever-growing demand for electrifying everything, we need more sustainable batteries. Li-ion devices are cost-effective but rely on lithium, graphite, and other materials, whose sourcing has significant environmental and social impacts. One potential solution is being developed where wood is used to replace these materials with a bio-based alternative.
The southwestern U.S. is in the throes of a “megadrought” so severe that we’ve broken the record — all 1,200 years of it. According to a study published earlier this year, soil hasn’t been this dry since the scientific record began around the year 800.1 This
I’m in the process of building a new energy efficient, net zero modular home that’s being built in a factory. Why did I choose this path versus one of the many other sustainable and energy efficient methods like stick built passive homes, ICF, earthships, etc. (fill in your
With electric vehicle demand skyrocketing and the growing need for energy storage for renewables, lithium-ion batteries are one of the key technologies for our sustainable future. However, “how sustainable?” is the million dollar question. Between the supply chain issues of the past couple of years and inflation, the cost of
There are a lot of different paths you can take to get to a net-zero home. Everything from passive homes to earthships to modular and factory built houses. You can retrofit an existing building or you can build a new one. All of the options can make your head spin
Solar power is on sale Maybe the biggest opportunity for homeowners is through the Residential Clean Energy Credit. The government is returning 30% of costs for installing solar energy in your home through federal tax credits. So for example, if you spend $10,000 setting up a solar power system,
