Funding Roundup: Lights, Solar, Money

The U.S. Department of Energy charges up energy-efficient lighting with $20.6 million, solar continues to shine for investors, a water deal swells with $20 million and Advanced Technology Ventures closes its eighth fund.

The U.S. Department of Energy said Tuesday it would help electrify efforts to bring energy-efficient lighting to market with up to $20.6 million.

Receiving the government's financial plug is a mix of 13 companies and research institutions. And since industry is expected to share in the costs, investment in the projects is expected to total $28 million.

The projects are aimed at advancing solid-state lighting, a technology that creates light with less heat than incandescent and fluorescent lamps.

Unlike incandescent and fluorescent bulbs, solid-state lighting uses a semiconducting material to convert electricity directly into light. The approach is known to improve light's energy efficiency.

It's not like such technology isn't already on the market. Think light-emitting diodes that light up digital alarm clocks and flat-screen televisions.

But the DOE thinks the sector can do much more, like double the efficiency of lighting systems.

Companies like Scotts Valley, Calif.-based Add-Vision and Green Island, N.Y.-based Crystal IS are among those to score the government's backing (For a complete list of companies and projects click here).

But energy efficiency isn't the only cleantech sector to see funds pour in lately. Below, check out a list of deals that went down over the last week.
