Do Geo-Engineering Win-Win-Win Spaces Exist?
Okay, I’ve set out a few ideas on principles, created a challenge. Is it a challenge that can realistically be met? Simply put: yes! Here are several paths to help contribute to dealing with temperature levels that go to a positive space in other arenas. Reflective Roofing: A typical ‘asphalt’ shingle/such roof, with a very low albedo factor (reflectivity) absorb substantial amounts of solar radiation through the year. Shifting to a reflective roofing material can send much of that solar radiation back to space. It is also highly cost effective because it can reduce air conditioning loads and increase roof longevity. Some payback analysis suggests that, when compared to ‘traditional’ roofing, reflective roofs can pay back the added cost in just a few weeks. Now, what about the heat/cooling impact globally? The Earth has an albedo of 0.29, meaning that it reflects 29 per cent of the sunlight that falls upon it. With an albedo of 0.1, towns absorb more sunlight than the global average. P
