Efforts to control climate change are falling short : NPR

The hottest year on record is coming to a close, emissions of planet-warming gases are still rising globally, and the most ambitious climate goal set by world leaders is all but impossible to meet, according to a new analysis by the United Nations.

The annual report from the U.N. Environment Programme lays out how far behind the world is on controlling planet-warming pollution, most of which comes from burning oil, gas and coal.

In a nutshell an inverter motor works like this …

|

1) Grid power supplies single phase, 120 or 240 volt AC power at 60 hz

2) That power is run through diodes to create 120 volt or 240 volt direct current

3) A microprocessor connected to three sets of IGBTs (essentially high power transistors) switches them on an off to create three phase power at a variable frequency

4) The three phase, variable frequency AC electricity drives a three phase motor – no losses from shaded poles or starting coils – or coasting between the two poles

5) By varying the frequency of the AC, you vary the speed of the AC motor efficiently

6) Also, you can have smaller coils if you drive the motor at a higher frequency then gear the motor down for power and speed desired

Proposed Solar Farms in New York State

|

This map shows all several additional solar farms proposed for New York, many of much larger scale then existing facilities. Yellow balloons are (L) Regulatory approvals pending. Not under construction, Light Blue means (T) Regulatory approvals received. Not under construction, and Green is (P) Planned for installation, but regulatory approvals not initiated.

11/8/23 - UPDATED with September 2023 DATA This is an interactive map, so make sure to Zoom in to see the exact location of proposed solar farm, and click the balloon to get the full data reported to the Energy Information Agency.
