Was there something extra in the Valentine's champagne this week? Or maybe those little blue pills were a little too potent?

Because it's been an extraordinary seven days in the business of cleantech/greentech investing, mergers and financing.

Headlines: ADM announced it's issuing $1 billion in notes. And Suntech closed on half a billion of its own (with so many convertibles flying around, you'd swear you were in California.)

This week:

• Agricultural and biofuel powerhouse Archer Daniels Midland is offering $1 billion of Convertible Senior Notes due 2014. The notes will be convertible under "certain circumstances." ADM plans to use the proceeds to buy back up to $400 million worth of its common shares and use the balance for general working capital. ADM is one of the world's largest processors of soybeans and corn (and, therefore, biodiesel and ethanol) and a variety of food and other products.
• Solar maker Suntech of China closed its own recent convertible notes offering this week. First it was to be $300 million (see Suntech raising another $300M.) Within a few days, it got upped to $425 million (see Suntech supersizes). The offering finally closed this week on a cool $500 million. Initial purchasers exercised their options to purchase up to an additional $75M USD of the notes, Suntech said. Nice problem to have.
• EnerNOC Inc., a Boston-based provider of demand response and energy management solutions, has filed for a $100 million IPO. It plans to trade on the Nasdaq under ticker symbol ENOC, with Credit Suisse and Morgan Stanley serving as co-lead underwriters.

Canaccord Adams and Jefferies & Company are to co-manage the IPO.
• Prism Solar Technologies of New York closed on a bridge round toward a Series A financing.

Prism is a maker of solar modules that utilize holographic optics to increase the output of a module while lowering the cost by reducing the number of cells required.
