His pain was transfixing, a case study in a fundamental climate riddle: How do you confront the truth of climate change when the very act of letting it in risked toppling your sanity? There is too much grief, too much suffering to bear. So we intellectualize. We rationalize. And too often, without even allowing ourselves to know we’re doing it, we turn away. At virtually every level — personal, political, policy, corporate — we repeat this pattern. We fail, or don’t even try, to rise to the challenge. Yes, there are the behemoth forces of power and money reinforcing the status quo. But even those of us who firmly believe we care very often fail to translate that caring into much action. We make polite, perhaps even impassioned conversation. We say smart climate things in the boardroom or classroom or kitchen or on the campaign trail. And then … there’s a gap, a great nothingness and inertia. What happens if a human — or to be precise, a climate scientist, both privileged and cursed to understand the depth of the problem — lets the full catastrophe in?
Why worry about the smell of the burning brakes on the steep hill as the truck only speeds up, when you got Sam Cooke's Twisting the Night Away, on the radio. Everybody, let's singing along ...
They're twistin', twistin' Everybody's feelin' great They're twistin', twistin' They're twistin' the night away
President Biden on Monday pledged to replace vehicles owned by the federal government with U.S.-made electric vehicles, doubling down on a similar campaign pledge.
“The federal government also owns an enormous fleet of vehicles which we're going to replace with clean, electric vehicles made right here in America by American workers,” he said while?discussing an executive order?aimed at increasing federal procurement of products made in the U.S.
Though mixing different solar panels is not recommended, it’s not forbidden and things would be ok as long as each panel’s electrical parameters (voltage, wattage, amps) are carefully considered.
When you intend to wire two panels produced by different vendors, the vendors are not the problem.
The problem is in different electrical characteristics of the panels, together with different performance degradation.
We put solar panels together to increase the solar-generated power.
In an effort to slow the nation's contribution to climate change, President Biden is expected to begin halting oil and gas leasing on federal lands and waters.
The much-anticipated move is one of several executive actions the president is scheduled to make Wednesday to address the worsening climate crisis and the broader decline of the natural world, but it won't come without pushback.
“I think we’ve got to find a better way to do it, because I think net metering is going to result in a pushback against residential solar,Θ said Richard Schmalensee, economics professor at MIT’s Sloan School of Management, on the sidelines of the report launch in Washington, .C.
All diodes violate ohms law as they are inherently non linear loads - which is why you can't use ohm's law to understand solar power or LEDs as they are diodes which conduct electricity in a non linear fashion.
If solar panels were linear their output would would be the same regardless of load but the silicon junctions are more efficient at certain current levels. That's why people use buck and boost converters to maximize their efficiency - and why most larger solar systems use MPPT controllers.
Likewise, if you limit the current and under drive LEDs they can be much more energy efficient and last longer. For example, two LEDs each driven at 10 mA will produce much more light than one LED driven at 20 mA, even though ohms law says that's impossible. This important - if you pack more LEDs in a light bulb and run them at lower current you can boost efficiency and lifespan at a greater cost of building the bulb.
I think it’s great the Joe Biden administration is making climate change a top priority of their agenda. There is a lot of advantages to the economy and society’s well being by reducing urban pollution, increasing efficiency and promoting electrification over direct burning of fossil fuels in urban neighborhoods. While we have to be cautious about the bold powers that any climate program is likely to give the government, we should move forward, away from traditional, highly-polluting ways of conducting business.
