Powering change: Energy production and consumption as seen through mosaic

Energy is, in large part, what got us into this climate change mess in the first place. The burning of fossil fuels like coal, natural gas, and oil has not been kind to the climate. So naturally, changing how we produce and consume energy—shifting to sustainable energy sources and reducing our consumption—will be an important part of taking action to reduce our climate footprint.

Let me be clear: when I’m talking about green or sustainable energy, I am not talking about things like “clean coal” (which is total greenwashing) or fracked natural gas (as much as some would like to tout this as a ‘transition fuel’ and celebrate its contribution to energy independence). No, when I talk about green energy, I am talking about truly renewable forms, like solar, wind, tidal, hydro (but more in the realm of micro-hydro and run-of-river than large-scale hydro), geothermal, and, in some cases, biomass. Yes, these all have an environmental footprint, as (fossil fuel industry–funded) opponents are fond of pointing out. There are impacts associated with the sourcing materials (e.g., mining) and production, with its transportation and construction, operation (e.g., impacts on wildlife like birds and bats), maintenance, and decommissioning. But anything we do—any form of energy we produce—has an environmental footprint, and the environmental footprint of renewable forms of energy is substantially smaller than that of fossil fuel energy. Of course, the greenest form of energy is the energy we don’t use at all and therefore don’t have to produce in the first place, also known as negawatts (‘negative megawatts’—a term coined by Amory Lovins in the 1980s).

“Power dynamic (Renewable production, mindful consumption)” (2017), 22″ x 11″ — marble, litovi, smalti, knob and tube, solar panel, shell, shale, limestone, sandstone, ceramic, miscellaneous stone

This mosaic tackles both renewable energy and sustainable consumption. Starting at the top, there is wind power, complete with clouds made of broken tubes from old knob and tube wiring (which were found in my dad’s garage, of course). Next up is solar power in the form of shiny rays of gold smalti. After that is all water-related forms of energy, but note that there’s lots of motion in the water (thanks to some waves made out of some really amazing shells)—no large problematic dams and reservoirs here!

Knob and tube clouds and golden sunny rays! (Plus negawatts. They’re everywhere!)

Sitting on the ground, there are solar panels ready to catch the sun’s rays above. These were originally part of solar-powered plastic flowers that decorated my grandma’s planter box, but when they broke I scooped them up rather than send them to the landfill. Around the solar panels is a layer of biomass, which, if done properly, is another source of green power (‘properly’ meaning not displacing food production or leading to deforestation, among other factors).

Some negawatts mixed into the biomass section

Water, solar, and biomass. Check, check, and check!

And finally, down into the earth for geothermal energy, with hints of the heated groundwater that will be tapped into to produce energy. And we can’t forget the negawatts! You’ll see small sections throughout the mosaic where there are just the impressions left by missing pieces. If we consider each individual piece in this mosaic as a megawatt (a unit of power), then those missing pieces are the negawatts: integrated throughout and an essential part of a comprehensive energy strategy.

Energy is a really easy area to take action on. You can buy green energy, you can install solar panels on your home, and you can also make your home more energy efficient through renovations (e.g., putting in extra insulation, sealing cracks, planting shade trees, etc.), technology upgrades (e.g., installing a smart thermostat, getting rid of that inefficient beer fridge), and behavioural changes (e.g., hanging your clothes to dry, turning off lights when they’re not in use, putting on a sweater and keeping your house a little cooler in the winter). There are usually incentive programs around to encourage you to implement these actions, so check with your local utility company or various levels of government. The nice thing about reducing your energy consumption is that it usually saves you money in addition to helping you feel very virtuous. Bonus!

And with that, I’m off to my renewable energy–powered studio to create my next climate change mosaic…
