There’s a solar energy revolution underway.

As the price of photovoltaic cells has declined (from upwards of $75 per watt in the late 1970s to around 75 cents today), energy from the sun has become cost-competitive with energy from fossil fuels in at least twenty states. In California, we now have the energy equivalent of a large coal-fired power plant sited on our rooftops. In 2012 alone, the amount of solar energy the United States produced increased by 500%.

And yet, some  75% of Americans still can’t go solar.

Mosaic was founded in order to make it possible for everyone to join the solar revolution by making it easy for anyone to directly invest in clean energy.

Last month, we listed our first four public solar project investments. Investors could lend a minimum of $25 to a project, and all of the projects had an expected annual return of 4.5%. Within 24 hours, the projects were sold out, with 435 investors lending more than $315,000.

We’re now getting lots of questions about when our next solar investments will go online. The answer is: very soon. And you can be sure to get in on this round by signing up now to invest in clean energy.

In the meantime, we also want to help out those of you who are able to go solar on your own home. We’ve created a tool that makes it easy to get free home solar quotes from a network of high-quality installers. Think of it as Expedia for rooftops.

More Tagging tips:

A tag is a way to search for this diary. If someone is searching for "Barack Obama," is this a diary they'd be trying to find?

Use a person's full name, without any title. Senator Obama may become President Obama, and Michelle Obama might run for office.

If your diary covers an election or elected official, use election tags, which are generally the state abbreviation followed by the office. CA-01 is the first district House seat. CA-Sen covers both senate races. NY-GOV covers the New York governor's race.

Tags do not compound: that is, "education reform" is a completely different tag from "education". A tag like "reform" alone is probably not meaningful.

Consider if one or more of these tags fits your diary: Civil Rights, Community, Congress, Culture, Economy, Education, Elections, Energy, Environment, Health Care, International, Labor, Law, Media, Meta, National Security, Science, Transportation, or White House. If your diary is specific to a state, consider adding the state (California, Texas, etc). Keep in mind, though, that there are many wonderful and important diaries that don't fit in any of these tags. Don't worry if yours doesn't.
