With oil prices cut in half and gasoline near (or below) $2 per gallon, is now a good time for the U.S. to end its century-long addiction to oil?

The topic was raised by none other than the 'liberal bastion' of The Wall Street Journal Monday (subscription required0 with energy analysts and policy makers weighing in.

BloggingStocks Monday asked Energy Trader Jim Dietz to evaluate some of the major recommendations discussed.

• Four-day work week: "It's possible, but the best plan would be voluntary, allowing companies to opt in/out and adopt plans that meet their production needs," Dietz said.

• Mandated higher MPG for vehicles: "This is almost certain to be proposed by President-elect Obama, and will likely pass the Congress. It will reduce gasoline and diesel consumption."

• Mandated flex-fuel cars: "Another measure likely to become federal law and it would take pressure off oil consumption."

• Tax credit for fuel-efficient vehicles: "Another oil saver, and it stands a better than 50% chance of being passed by the next Congress."
  

• Federal funds for next-gen vehicle: "This will likely be included in any rescue package for General Motors, Ford, and Chrysler. A next-generation vehicle would be a game-changer, energy wise, but it's years away."

Over 32 years, the portfolio in The Oberweis Report has returned an average gain of 21.2% a year vs. 7.9% for the S&P 500. Here, money manager and newsletter advisor Jim Oberweis, Jr. looks at Suntech Power Holdings Ltd. (NYSE: STP).

"Long-term results notwithstanding, 2008 has been humbling, to say the least. No other year in our history has been as challenging.

"But in our experience, the most favorable buying opportunities tend to fall after a period in which the market has not performed well.

"Although year-by-year results can be volatile, disciplined investors who remain fully invested in a portfolio of high-growth equities selected using our methodology have historically achieved an exceptional average rate of return over long periods of time.

"Suntech Power Holdings Co., Ltd is one of the leading solar energy companies in the world as measured by production output of photovoltaic, or PV, cells, with leading positions in key solar markets such as Germany and Spain.

Analyst Michael Molnar of Goldman Sachs took a harsh tone on the solar sector today, slashing his opinion to Sell on both First Solar, Inc. (NASDAQ: FSLR) and SunPower Corp. (NASDAQ: SPWRA). Specifically, First Solar was slashed to Conviction Sell from Buy, while SunPower was dropped from Buy to Sell. In a note to clients, Molnar explained, "We strongly believe that SunPower and First Solar are two of the best solar companies in the world and that both will be part of the growing solar industry for years to come. However, in our view, even these companies will face headwinds in a market that is oversupplied with modules."

Specifically, "the risk of oversupply in the solar market will soon become a reality as considerably less generous demand subsidies take hold just as a wave of supply and tight financing hit the market," said Molnar. He added, "We believe that liberal subsidies of the past in markets like Germany and Spain are unlikely to be replicated in the future, given fears of their ultimate cost in a bad world economy."

As a whole, Goldman maintains a "cautious" view of the solar sector -- and the brokerage firm isn't alone. Piper Jaffray also weighed in on solar firms today, with a warning that higher credit costs could reduce average selling prices by an additional 6%. "The renewables industry depends on access to credit, and for the moment, the credit market remains closed," Piper stated. "We believe the cost of capital on renewable projects will increase due to higher bank financed interest rates, larger spreads, and more upfront fees." For 2009, Piper Jaffray predicts that companies' average selling prices will fall by 15% to 21%.

This post is part of a series in which TheStockAdvisors.com asked financial experts to name their top stock pick if McCain or if Obama wins the election.

"An Obama administration is likely to be very aggressive in subsidizing and promoting alternatives, including a windfall tax on oil firms to support development of alternative energy; SunPower Corp. (NASDAQ: SPWR) is our pick to play an Obama victory," says Elliott Gue in The Energy Strategist.

"Obama's energy plan calls for generating 10% of electricity from renewable sources by 2012 and 25% by 2025, an aggressive goal when you consider that less than 3% of America's power comes from non-hydropower renewables today.

"Obama has also proposed a windfall tax on oil companies that would be used to support the development of alternatives like solar and wind power.

"SunPower manufactures and sells photovoltaic (PV) solar panels for the residential, commercial and utility-scale markets.

"Residential and commercial solar systems are solar panels installed on the roofs of homes and businesses, designed to supplement power supply from the electric grid.

"And SunPower recently won a contract with Florida-based utility FPL to build the largest photovoltaic plant in North America, a 25 megawatt utility-scale plant in DeSoto County, Florida.

Wind and solar, two renewable energy sources with a promising future, nevertheless face a bottleneck of sorts in the United States: the electric power grid. The existing grid can not handle the new demands, The New York Times reported Wednesday, forcing renewable wind and solar sites to shut down, even when conditions are right to generate and sell power.

An infrastructure-challenged U.S.

Economist Glen Langan says there's a theme that keeps popping up in the U.S. economy in the early 21st century: inadequate infrastructure. "We're a nation of inadequate infrastructures: the power grid, air travel/air traffic control, railways, highways... pick an infrastructure and you'll see a network that can't handle present demands, let alone an expanded national economy in 2020 or 2030," Langan said.

The power grid bottleneck is particularly frustrating and damaging because both wind and solar power generation systems are mushrooming, and could, with an adequate grid, account for more than 20% of the nation's power needs, Langan said, adding that some economic models put renewable energy's potential contribution even higher, at 25% or more.

"Imagine T. Boone Pickens building his massive, multi-billion dollar wind mill farm and having it sit idle because the grid cannot tolerate and transmit the increased power? Pretty sad," Langan said.

"There's no 'silver bullet' solution to the energy crisis; but there are some solutions that do work," says Sean Broderick, referring to wind and solar power.

In The Safe Money Report he says, "There are with some choice ETF to power your own bottom line." Here's a look at the two green technologies and how you can invest in these developing fields.

"Many Americans are disgusted by the fact that, faced with an energy crisis, the government seems to produce nothing but hot air. So let me give you my appraisal of two alternative energy solutions that work -- along with some choice exchange-traded funds that can power your own bottom line. Here are two energy solutions that work right now.

Solution #1: Wind Power

"Critics will point out that the wind seems to stop blowing when you want electricity most -- on hot summer days. And that is a problem. However, a study last year by Stanford University shows that wind power from interconnected farms can be used as reliable base load electric power.

"To say that alternative energies are critical is a severe understatement." asserts Stephen Leeb, who looks at three plays in the sector that earn a spot in his Growth Portfolio.

The editor of The Complete Investor explains, "Readily scalable energy sources such as solar and wind account for under 1%. It's time to get serious."

Three of the stocks he has selected are holdings in his model Growth Portfolio: FPL Group (NYSE: FPL), Exelon (NYSE: EXC), and General Electric (NYSE: GE). Here's a trio of favorites.

"We have focused on those alternative energy stocks with the strongest growth profiles. None is a pie in the sky fantasy; all provide energy in the here and now and have significant and fast-growing revenue streams.

"The fact that their growth should continue to burgeon is one of the most heartening pieces of news on the energy front. We could argue that investing in these stocks not only will be good for your portfolio but is an act of patriotism as well.

Almost on cue, following oil's $12 rise in two days to $134, the International Energy Agency said the world needs to invest an additional $45 trillion in the decades ahead to vastly expand both nuclear power and wind power capacity to meet global energy needs.

Strictly speaking, the IEA's call to action was rooted in reducing the world's greenhouse gas emissions and achieving what it argues will be "a clean, clever, energy future" and not to move away from oil or fossil fuels solely on cost grounds. (pdf)

Still, the report's 2050 ETP Baseline scenario projects that CO2 emissions will rise by 130% and oil demand will rise by 70% - - the latter total being equal to five times Saudi Arabia's current oil production. If the IEA's oil projection is correct, that would suggest additional large increases in the price of oil in the decades ahead - - on top of oil's more than 400% price rise since 2001.

Solar energy may be the wave of energy's future, but companies such as Google (NASDAQ: GOOG) and Chevron (NYSE: CVX) may best start-ups in getting to the benefits. A number of large American companies with tremendous balance sheets are pouring money into solar energy based on the fact that it is becoming more competitive with oil.

According to Bloomberg, "Costs for the technology will fall below coal as soon as 2020, the U.S. government estimates. JPMorgan Chase & Co. and Wells Fargo & Co. invested last year in the biggest solar plant built in a generation; Chevron and Google are funding research; and Goldman Sachs is seeking land to lease as demand out-paces wind turbines and geothermal."

Given the potential size of the bonanza, the investments should not be surprising, but they could squeeze smaller solar energy companies out of the market. Firms like JA Solar (NASDAQ: JASO) and SunTech (NYSE: STP) have their entire futures bet on the success of solar energy and the fact that there are not many companies in the business, at least until now.

It has began to occur to large companies that if fossil fuels will indeed start to run low in two or three decades that the trillions of dollars in market cap currently represented in large oil company stocks will have to go somewhere.

Why not to Google?

"Oil is setting the stage for a big rally in alternative energy," says Eric Roseman, resources expert and editor of Commodity Trend Alert. Here's a look at two stocks poised to benefit from this trend.

"A surging oil price is extremely bullish for alternative energy. Over the last 12 months, as oil prices have doubled, uranium and solar energy stocks have crashed.

"These sectors have declined because sub-prime has taken everything to the basement until recently - not because solar energy or uranium are flawed investment themes.

"That's why we've recently placed new trades on Suntech Power Holdings (NYSE: STP) and Cameco (NYSE: CCJ). There's no way high oil prices won't encourage more interest in these distressed sectors.

SunPower (NASDAQ: SPWR) recently down $13.11 to $86.55:

Cowen says "SPWR again exceeded expectations and raised 2008 guidance on strong future outlook." SPWR call option volume of 39,724 contracts compared to put volume of 21,724 contracts. SPWR May option implied volatility of 74 was above its 26-week average of 68 according to Track Data, suggesting larger movement.

Evergreen Solar Inc. (NASDAQ: ESLR) shares are trading higher after the company announced it has started an expansion project to double the capacity of its Devens, Mass., plant to 160 megawatts by the end of next year. If you think that the stock won't fall by too much in the coming months, then now could be a good time to look at a bullish hedged trade on ESLR.

After hitting a one-year high of $18.85 in December, the stock hit a one-year low of $7.52 in March. ESLR opened this morning at $11.66. So far today the stock has hit a low of $11.10 and a high of $11.97. As of 12:30, ESLR is trading at $11.27, up $0.57 (5.3%). The chart for ESLR is bearish but improving, while S&P gives the stock a bullish 4 Stars (out of 5) Buy rating.

For a bullish hedged play on this stock, I would consider a September bull-put credit spread below the $7.50 range. A bull-put credit spread is an options position that combines the purchase and sale of put options to hedge risk in case the stock doesn't do what you think but still leverage nice returns. For this particular trade, we will make a 16.3% return in just five and a half months as long as ESLR is above $7.50 at September expiration. Evergreen would have to fall by more than 33% before we would start to lose money.

ESLR hasn't been below $7.50 at all in the past year and has shown support around $9 recently. This trade could be risky if the prices for oil and other energies fall off some in the coming months, but even if that happens, that position could be protected by support the stock might find just above $7.50, where it bottomed out in the past month.

Brent Archer is an options analyst and writer at Investors Observer. At publication time, Brent neither owns nor controls positions in ESLR.

The oil market, to put it diplomatically, has not provided a great deal of encouragement lately for policy makers attempting to stimulate U.S. economic growth.

Further, time was when an $80 or $85 price would be considered unreasonably high, or even outlandish. But given oil's breakthrough and close above key, psychological resistance of $100 per barrel this week, $80 looks almost like an acceptable price.

Moreover, oil mogul and billionaire T. Boone Pickens says we may get there. Providing a ray of light for concerned business executives, consumers and public officials, Pickens, who accurately predicted oil's rise to $100 per barrel, told CNBC Thursday oil should drop $10-15 in the second quarter of 2008.

"I think oil's going to back off," Pickens said during the interview. "The weakest quarter is the second quarter. We'll drop $10 or $15 a barrel in the second quarter. I think we'll be back above $100 in the second half of the year."

The choppy/consolidating (or perhaps worse) market conditions sometimes give the impression that growth plays do not exist. That is not the case, and one growth company worth reviewing is Cypress Semiconductor.

Cypress Semiconductor (NYSE: CY) is a manufacturer of high-performance integrated circuits, memory chips and silicon solar cells.

Analysts really like Cypress' revenue growth prospects of 23-25% following a likely 45-50% increase in 2007.

Analysts also like Cypress' recent acquisition of PowerLight Corp. and expect the purchase to drive a significant earnings increase. CY's SunPower business is another plus, due to its potential growth and undervalued status.

Two of the digital-age growth trends include semiconductors and solar power, so when one can potentially capitalize on both in one stock, it makes for an appealing investment opportunity. MEMC Electronic Materials does just that.

MEMC Electronic Materials (NYSE: WFR) designs, manufactures and provides wafers and intermediate products for use in the semiconductor, solar and related industries.

Analysts see 2008 revenue increasing 20-30% after a likely solid 23-27% increase in 2007. Backorders also are impressive. Meanwhile, the sector's outlook provides additional cause for optimism, with solid demand for both solar wafers and semi wafers seen in the immediate years ahead.
