Greentech stocks, across clean power, biofuels, smart grid, batteries and electric vehicles, took it on the chin in the market sell-off yesterday — the first day of trading after the Standard & Poor downgraded the credit ratings of credit agencies. Well, the entire market did. But the market is rebounding slightly on Tuesday, and greentech stocks got bumped up a bit along with the rest of ’em.

A few of the stocks I covered yesterday are still down — like EnerNOC (s ENOC), but that’s due to company-specific issues. Most are slightly up, though many didn’t return to the trading levels pre-market sell-off. Here’s a run down on where the stocks I covered yesterday are at this morning:

Solar

• Solar panel maker SunPower (s spwra) up 3.06 percent.
• Chinese solar panel maker Suntech (s stp) rises 4.13 percent.
• Thin-film solar maker First Solar (s fslr) is still down .40 percent.

Biofuels

• Biofuel maker Gevo (s gevo) is back up 10.87 percent.
• Algae oil company Solazyme (s szym) is up 3.07 percent.
• Biofuel maker KiOR (s kior) is down even more: 3.50 percent.
• Biofuel maker Amyris (s amrs) is up 0.75 percent.

Electric car and batteries

• Lithium ion battery maker A123 Systems (s aone) is up 11.70 percent.
• Electric car maker Tesla Motors (s tsla) is up 5.67 percent.
• Battery maker Ener1 (s hev) is up 6.75 percent.

Smart grid

• Smart meter and network maker Itron (s itri) is up 5.14 percent.
• Demand response company Comverge (s comv) is down even more, by 1.38 percent.
• Demand response leader EnerNOC crashed even more, by 36.98 percent (s enoc). (Yesterday’s market crash is combined with EnerNOC’s own weak earnings statement and a downgraded position to hold by a prominent analyst).
• Smart meter and network maker Echelon (s elon) is back up by 5.51 percent.

Random:

• Car sharing company Zipcar (s zip) is up 2.75 percent. It hasn’t fully recovered from yesterday.
• Clean Energy Fuels (s clne), which makes natural gas infrastructure for gas-powered cars, is still down by 5.80 percent.
