Remember - it’s now #grokgreen
Here is the hashtag for my efforts in unpacking some of the heavy and confusing words in sustainability, buildings, energy, policy. #graspgreen The simple explanations will be from my experiences. I’ll make it clear when snark enters the posts!!

More on pervious surfaces and benefits.

We (UpstateNY) have a pervious asphalt driveway. It cost about 10% more 8 years ago. It reduced basement flooding and is lasting great.

We use our leaf blower in reverse 2x a year to clean it. Less shoveling in the winter, no $ on salt or sand.

“Pervious” - #water can flow through. Most concrete, asphalt, pavers, and hard packed soil is impervious. The rainfall runs off, and never soaks into the soil.

A complete cycle means water gets into the soil and is filtered naturally. This helps #soil quality and #aquifer resilience.

RECs (renewable energy credits) track the production and use. RECs can be a carbon offset strategy.

RECs can be falsely sold while the electricity is used by the owner of the panels. Also some RECs are “outdated”.

The best RECs are 3rd party certified and invest in NEW production.

#grokgreen This impacts EVERYONE in cities. #UHI - Urban Heat Island impact.

Dark surfaces and impervious areas (no water can drain) + lack of plants to help transpire water to air, raise the ambient temp in cities 15-20 degrees.

Plants, lighter colors, pervious hard surfaces, are all a benefit.

“Renewable energy”, often abbreviated as RE, usually refers to energy produced by wind, sun, or wave actions.
Some policy language says geo-thermal (heat exchange from the earth) is RE, but that (and other sources) is debated.
RE does not burn fuel, though production of the components often does.

“Decarbonization”. In buildings and in policy, this is about #electrifying the existing systems.

Reducing #energy use, then replacing heating and cooling as well as cooking(!) with electric systems.

Electricity can transition to all renewable sources, over time. Fossil fuel can’t. #grokgreen

1/ Just saw a post about insulation. “R -value” is the resistance to heat transfer through materials. Often used 4 insulation: energy code “prescriptive” method dictates only insulation performance (so far). But insulation is used in walls with studs (wood or metal) which have crappy Rs.

Hah! Better (I changed my mind) it will be #grokgreen. So much better.
