Why do experts always lowball clean energy projections?

Last month, Michael Noble of Fresh Energy put up a fascinating list of projections made by energy experts around 2000 or so. Suffice to say, the projections did not fare well 버즈런처. They were badly wrong…

What should we take from this?

The projections weren’t just off, they were way off. You can find similarly poor projections from the ’70s that underestimate the spread of energy efficiency and other demand-side technology solutions (They thought they were going to need hundreds of nuclear plants) Tinyumbrella download. Similarly terrible projections were also common in the early years of cell phones.

What do cell phones, energy efficiency, and renewable energy have in common 무한의 탐정2 다운로드? One, they are dynamic areas of technology development and market competition, which makes straight-line projections pretty useless. And two, they are distributed, with millions of loosely networked people and organizations working on them in parallel 탈옥 유튜브 다운로드. Distributed, human-scale technologies come in small increments. They replicate quickly, so there’s more variation and competitive selection, and thus more evolution 다운로드.

This is what Global Warming looks like

“This is what global warming looks like at the regional or personal level,” said Jonathan Overpeck, professor of geosciences and atmospheric sciences at the University of Arizona code39 폰트 다운로드. “The extra heat increases the odds of worse heat waves, droughts, storms and wildfire. This is certainly what I and many other climate scientists have been warning about.”

Horrendous wildfires 다운로드. Oppressive heat waves. Devastating droughts. Flooding from giant deluges. And a powerful freak wind storm called a derecho.

These are the kinds of extremes experts have predicted will come with climate change, although it’s far too early to say that is the cause 다운로드. Nor will they say global warming is the reason 3,215 daily high temperature records were set in the month of June.

Scientifically linking individual weather events to climate change takes intensive study, complicated mathematics, computer models and lots of time 휴직증명서 다운로드. Sometimes it isn’t caused by global warming. Weather is always variable; freak things happen.

Shakespeare’s Restless World – fascinating new podcast from BBC Radio 4

British Museum Director Neil MacGregor presents Shakespeare’s Restless World, a new series for Radio 4 소닉 앤 너클즈 다운로드. The 20-part series looks at the world through the eyes of Shakespeare’s audience by exploring objects from that turbulent period.
