Soaring oil prices have led to such a boom for solar power that the industry could operate without subsidies in just a few years.

According to The Guardian newspaper, there’s growing confidence that so-called “grid parity”, the holy grail of the industry — whereby solar power can be produced as cheaply as it bought from the grid — is close at hand.

“The [US]  government recently incentivized production of ethanol, biofuel, and solar technology,” says Charles Delvalle in Investor’s Daily Edge.

If a Democrat gets into office, these incentives should grow. Congress even pushed up the Corporate Average Fuel Economy (CAFÉ) guidelines for the first time since 1975. And the idea of carbon credits is beginning to gain traction in Congress.

So the government is helping fuel the creation of cleaner energy. Step one is complete.

What about step two?

If I talk to any of my friends and tell them I love the things oil does to the earth, they’ll slap me (yes, I know oil is bad for the earth). If I told them that I didn’t recycle, they’d yell at me (yes, I recycle). My friends are already convinced that the green movement is the way to go.

If you type in the word ‘green’ in Google, you’ll see thousands of new websites that all talk about how great it is to be green.

Look at corporate trends, and you see more commercials with companies talking about going green. Wal-Mart, IBM, Intel, Google, and even ExxonMobil is getting into the act. The idea of going green is spreading like wildfire. And it will only increase as gas prices move higher.

The green market is definitely seeing the second step. But how about the third?

Have you seen solar stocks lately? In the past two years, these companies have popped by 100% - 300%. And it seems like a new solar company pops up every other day touting a ‘breakthrough’ technology that allows amazing conversion of light to electricity. Many have no profits to speak of and don’t plan on entering production for years.

Ethanol stocks were moving higher for a while, but have gone down since the middle of last year (maybe investors are catching on to how ‘not green’ ethanol really is). Geothermal producers are shooting higher. And those who sell wind turbines are making great money on increasing orders.

By 2030, Morgan Stanley expects green sales across the globe to total over $1 trillion (that’s bigger than the Gross Domestic Product of 169 of the 181 member countries of the International Monetary Fund!).

Most people I speak to see green technology as the wave of the future. It’ll only be a matter of time until they think that investing in green companies is a no-brainer.

In the end, this whole green movement we see today could very well be the start of yet another massive bubble. And considering the riches that were made during the two previous bubbles, catching the green investment mania early on would be a great way to make a lot of coin in the next few years.

“The richest investment opportunities can be found in the fast-emerging alternative energy sector,” says Mike Burnick in The Offshore A-Letter.

That’s where oilman T. Boone Pickens is putting his money – his company Mesa Power just placed an order for US$2 billion in wind turbines. And there’s much more profit potential in other parts of the alternative energy sector too – especially alternative fuel.

The market for ALL alternative energy sources grew 40% last year alone to US$77.3 billion and will explode into a US$250 billion industry within 10 years.

Bio-fuel grew to a US$25.4 billion market last with more than 15 billion gallons of ethanol and biodiesel produced globally – more than double the output of just four years ago. The worldwide Bio-fuel industry will continue to enjoy explosive growth for years to come - expanding into a US$81 billion business within the next 10-years!
