Yes, we produce more solar and wind power, but the level of electricity consumption has also increased. Are we outputting less CO2 for electricity, or does all the solar and wind just come on top of what we already had?
I expect China's emissions to be through the roof compared to 1990, on the other hand they've noticed the problem and unlike Trump's head in the sand approach, the vast majority of their energy investments are in renewables.
So things are bad but they're looking up.

Grandparent was talking about investments, though, not the status quo. Couldn't readily find figures relating to the distribution of investments, but it's easy to find articles about the large scope of their renewable ambitions, e.g. http://www.wri.org/blog/2017/01/china-leaving-us-behind-clea...

> technology to reduce CO2 emission, assuming the same level of electricity consumption -- is far from being available. They had talked about Nuclear, sun, geo, nuclear fusion.
Solar and wind power are picking up steam (pun intendend :p).
> incandescent light bulb converts only 5% to light If larger city (NY, Moscow, Bombay etc) switch to better light bulb, 1 million ton of C02 emissions every year, each.
Incadescent light bulbs are largely obsolete. I'm sure they haven't been replaced 100% but they definitely are on their way out.
> simply changing from coal to gas cuts carbon emission by 40%
This is also happening cause gas is very cheap right now.
