New Cannabis Industry Leaving Quite the Carbon Footprint
The burgeoning legal marijuana industry is putting pressure on public utilities, using tremendous amounts of power to grow its plants indoors, shielding them from the elements and thieves alike.
What's the Latest?
The burgeoning legal marijuana industry is putting pressure on public utilities, using tremendous amounts of power to grow its plants indoors, shielding them from the elements and thieves alike. "The warehouses commonly used to raise the plants in large quantities use about as much energy per square meter as a high-end data center. One-third of the energy used in growing operations comes from the lighting; the rest is devoted to ventilation, heating, dehumidification, and air conditioning." Taken as a whole, legal marijuana growth accounts for $6 billion in US electricity costs.
What's the Big Idea?
Public utility officials are already making trips to large growth factories, looking for ways to improve their energy efficiency. And while reducing electricity use in homes often means replacing incandescent bulbs with CFLs or LEDs, large industry has a more diverse set of concerns. LEDs for example are costly and, depending on their photon output, affect the ratio of active components in marijuana plants. As growing marijuana becomes more commonplace, the amount of energy needed for indoor grow houses may become difficult to justify. Many progressive growers, in fact, are building outdoor greenhouses that can use sunlight for free.

Giving our solar system a "slap in the face."
- A stream of galactic debris is hurtling at us, pulling dark matter along with it
- It's traveling so quickly it's been described as a hurricane of dark matter
- Scientists are excited to set their particle detectors at the onslffaught
Two massive clouds of dust in orbit around the Earth have been discussed for years and finally proven to exist.
- Hungarian astronomers have proven the existence of two "pseudo-satellites" in orbit around the earth.
- These dust clouds were first discovered in the sixties, but are so difficult to spot that scientists have debated their existence since then.
- The findings may be used to decide where to put satellites in the future and will have to be considered when interplanetary space missions are undertaken.
Once again, our circadian rhythm points the way.
- Seven individuals were locked inside a windowless, internetless room for 37 days.
- While at rest, they burned 130 more calories at 5 p.m. than at 5 a.m.
- Morning time again shown not to be the best time to eat.
