Editorial Australia Youre All Alone

Editorial Australia Youre All Alone
Australia's new Prime Minister Tony Abbott, not a friend of the environment.

The leader of the right wing party, The Liberals Tony Abbott, has been elected Australia's new Prime Minister taking over the reins from Labor's Kevin Rudd.

There is no real surprise in that as it was believed for a while that voters had lost their faith in the Labor party amidst concerns around the economy. The Murdoch owned press, which is one of the biggest backers to Abbott and his party, had done their best to inform people that the carbon tax introduced by the then Prime Minister Julia Gillard would hurt the Australian economy.

One of Tony Abbott's election pledges was that he would scrap the carbon tax, triple the country's coal exports and get rid of green tape regulations. He has also stated that the argument that climate change is happening, is highly contentious.

While you should not kick a government before they have even come into power, we must remain very critical that the party which will run the government adopts a stance in not believing in climate change. Were they to adopt those views into the newly formed government, it would be one of few UN recognised governments who holds that view since the Bush Administration.

It's extraordinary given the year of weather extremes Australia has experienced that any person let alone a whole party can adopt those views. The cost to the Australian economy for those weather events is immense.

On top of that, Australia is basing their economy on mining, especially coal which scientists say further expansion will put Australia's greatest tourist attraction, The Great Barrier Reef, under great risk - again a great financial cost. At a time when most countries are looking to turn away from coal, one can greatly question the economics in making the country the world's biggest exporter, who do they envisage will buy it?

The tape Abbott and his government should consider getting rid of is the red tape almost prohibiting and discouraging renewable energy developments in some states. Australia has ideal conditions for renewable energy, large wind, solar and geothermal development. If Abbott really is serious about creating jobs and growing the economy, and not just making the richest corporations even richer, then he could do worse than kick-starting a renewable revolution down under.

New Nrel Study Highlights Benefits Of Solar Loans Vs Solar Leases And Ppas

New Nrel Study Highlights Benefits Of Solar Loans Vs Solar Leases And Ppas
Solar loans are gaining popularity as a solar financing option across the country. Because of the superior savings and similar benefits that solar loans promise, some industry analysts now predict that they will overtake third party-owned (TPO) solar leases and power purchase agreements (PPAs) as the dominant option for solar financing in the USA within a few years.

A new report from the National Renewable Energy Laboratory (NREL) examines this phenomenon and sheds more light on the possible advantages of financing your solar system with a loan as opposed to TPO solar lease / PPA.

THE MOST IMPORTANT CONCLUSION OF THE REPORT IS THIS: WHILE GOING SOLAR WITH EITHER OF THESE OPTIONS IS LIKELY SAVE YOU MONEY ON YOUR ELECTRICITY BILLS, FINANCING YOUR SYSTEM WITH A SOLAR LOAN COULD SAVE YOU UP TO 30% MORE THAN IF YOU GO SOLAR WITH A SOLAR LEASE OR PPA.

KEY TAKEAWAYS: BENEFITS OF SOLAR LOANS VS SOLAR LEASES

*

Consumers increasingly have access to no-money-down solar loans. These loans can be secured with your home or unsecured. You can get these loans directly from banks or through solar installers. (Learn more about solar loans.)

*

Solar loans could end up displacing third party-owned (TPO) solar leases and power purchase agreements (PPAs) as the dominant form of solar energy system financing in the USA within a few years.

*

Depending on the loan term, financing your solar system with a solar loan could save you up to 45% off your electricity bills over a 20-year period. Going solar with a zero-down power purchase agreement (PPA) could save you around 22% off your power bills over the same period.

*

Two useful figures to look at when considering whether a solar lease or a solar loan is more appropriate for you are a) levelized cost of energy (LCOE) and b) cash flow. LCOE makes it easy to compare long-term savings from different financing options. Looking at the annual cashflow of a financing option will give you an idea of how much money you will be spending or saving on a yearly basis.

*

Depending on the term, a solar loan could offer lower monthly payments and greater long-term savings than a TPO solar lease or PPA system.

*

Financing a system with a solar loan means that you are the owner and therefore financially responsible for maintenance and repairs. Unlike with a PPA, your system has no clearly defined 'production minimum', and you will not be compensated for any lost electricity production if your system fails to perform as expected.

LOAN, LEASE OR DO NOTHING?

The report takes a look at the rapidly expanding solar loan market in the US (with a focus on California), examining loan products for both residential and commercial solar installations. Titled "Banking on Solar: An Analysis of Banking Opportunities in the US Distributed Photovoltaic Market", it provides an overview of the relative benefits of going solar with a loan as opposed to going solar with a PPA - and compares both of these options to a 'do nothing - save nothing' scenario in which you continue paying your standard electricity bill.

But how do you compare the value of a lease/PPA - which is not an investment and therefore does not need to 'pay for itself' - to the value of a solar system you own? Levelized cost of energy (LCOE) and cash flow are two useful things to look at when comparing options, and to help you determine which solar financing option is best for you.

LEVELIZED COST OF ENERGY (LCOE)

The metric frequently used in the electricity industry for this purpose is 'levelized cost of energy' (LCOE). LCOE allows you to understand how much you will pay on average per unit (kilowatt-hour or kWh) of electricity over a set period of time. It is therefore useful in making apples-to-apples comparisons of your options. To determine the LCOE of a given electricity option, you estimate how much money you will spend on electricity over a given period of time (in the case of the report, 20 years), and divide that by the total number of kWh's you estimate you will have consumed in the same period. This will yield you a tidy dollar-per-kilowatt-hour (/kWh) figure that is easy to compare across electricity sources.

The table below compares the LCOE for three durations of solar loans (5-year, 10-year and 20-year) to the LCOE for a 20-year solar PPA, as well as the LCOE for standard electricity bill payments to your utility over a 20-year period. As you can see, solar energy systems financed with loans generally have the lowest LCOE of all the options - and the shorter the loan term, the lower its LCOE is. For example, financing with a 5-year solar loan will save you approximately 4% more on your power bills than financing it with a 10-year loan, and about 12% more than financing with a 20-year loan. Nevertheless, financing with a 20-year loan will still save you up to 19% more than financing with a 20-year PPA.

"PLEASE NOTE THAT FIGURES IN THE TABLE ARE INDICATIVE ESTIMATES ONLY, AND THAT YOU SHOULD LOOK INTO THE OPTIONS ARE AVAILABLE TO YOU BEFORE YOU MAKE A DECISION. ENERGYSAGE'S SOLAR MARKETPLACE CAN HELP YOU FIND AND COMPARE YOUR SOLAR LOAN OPTIONS, AS WELL AS THE INSTALLATION COMPANIES WHO OFFER THEM."

CASH FLOW


LCOE isn't quite the whole story, however: A second big consideration that the report takes note of is cash flow. While the LCOE numbers above may give you an idea of how much you will pay for electricity "on average" over the course of 20 years, how your payments are distributed throughout that period will vary. As you can see in the table below, your electricity expenditures in the first 5 years would be highest with the 5-year loan. After the 5 years, of course, the solar electricity produced is virtually 'free' besides regular maintenance (including replacing the inverter after about 10 years). By contrast, a system financed with 10-year solar loan could deliver an immediate reduction in your electricity costs.

You'll note that lines representing both the SDG&E rates (light blue) and the 20-year PPA (purple) rise gradually as time progresses, while loan payments are mostly flat until the loan is paid off. This is because contractual rates under a solar PPA will usually be subject to an 'escalator' of about 1-3% per year, and retail electricity rates are subject to 'utility inflation' of around 4.5-5% per year. If a system is financed with a loan, on the other hand, the owner will be responsible for any maintenance that is required. The spike at the 10 year mark for all of the loans in the table below represents the costs associated with the replacement of an inverter.

Figure ES-2. Comparison of annual payment between residential PV systems, financed under a PPA or loan, and retail rates (San Diego Gas & Electric). The spikes at the 10-year mark, representing the cost of inverter replacement, do not apply for a PPA. Source: NREL.

FINANCIAL AND OPERATIONAL RISKS:


Although purchasing a system with a solar loan will most likely save you more money over the long run, you should also be aware of certain risks associated with solar loans which don't apply if you go solar with a solar lease or PPA. These risks can be divided into two categories: financial risks and operational risks.

The savings in the graphs above are dependent on certain assumptions about your financial situation, as well as how the system will perform over 20 years. One example of a financial risk is a change in your credit rating. A drop in your credit score during loan repayment could result in higher interest rates being applied to your loan, which will impact the amount of time it takes to pay it off.

Operational risks have to do with the performance of your solar energy system. Under a solar lease or PPA agreement, all maintenance and repair costs are the responsibility of the third party owner - not you. Solar leases and PPAs also usually come with guaranteed production minimums, and if the system produces less power than agreed in the contract, you will be reimbursed. By contrast, with a solar loan, you are the owner of the system, and therefore repairs and maintenance are your responsibility. In practice, this is not a major concern, as solar energy system components are fairly durable and come with robust warranties. But it is something that you should be aware of if you think that a solar loan is right for you.

Elon Musks Tesla Master Plan

Elon Musks Tesla Master Plan
Back in 2006, Elon Musk published a blog post about his future plans for Tesla and electrification of the environment. It is remarkable how closely this planning has been followed nearly 10 years later. Here's the entire piece:

"Background: My day job is running a space transportation company called SpaceX, but on the side I am the chairman of Tesla Motors and help formulate the business and product strategy with Martin and the rest of the team. I have also been Tesla Motor's primary funding source from when the company was just three people and a business plan."

As you know, the initial product of Tesla Motors is a high performance electric sports car called the Tesla Roadster. However, some readers may not be aware of the fact that our long term plan is to build a wide range of models, including affordably priced family cars. This is because the overarching purpose of Tesla Motors (and the reason I am funding the company) is to help expedite the move from a mine-and-burn hydrocarbon economy towards a solar electric economy, which I believe to be the primary, but not exclusive, sustainable solution.

Critical to making that happen is an electric car without compromises, which is why the Tesla Roadster is designed to beat a gasoline sports car like a Porsche or Ferrari in a head to head showdown. Then, over and above that fact, it has twice the energy efficiency of a Prius. Even so, some may question whether this actually does any good for the world. Are we really in need of another high performance sports car? Will it actually make a difference to global carbon emissions?

Well, the answers are no and not much. However, that misses the point, unless you understand the secret master plan alluded to above. Almost any new technology initially has high unit cost before it can be optimized and this is no less true for electric cars. The strategy of Tesla is to enter at the high end of the market, where customers are prepared to pay a premium, and then drive down market as fast as possible to higher unit volume and lower prices with each successive model.

Without giving away too much, I can say that the second model will be a sporty four door family car at roughly half the 89k price point of the Tesla Roadster and the third model will be even more affordable. In keeping with a fast growing technology company, all free cash flow is plowed back into R&D to drive down the costs and bring the follow on products to market as fast as possible. When someone buys the Tesla Roadster sports car, they are actually helping pay for development of the low cost family car.

Now I'd like to address two repeated arguments against electric vehicles - battery disposal and power plant emissions. The answer to the first is short and simple, the second requires a bit of math:

BATTERIES THAT ARE NOT TOXIC TO THE ENVIRONMENT!

I wouldn't recommend them as a dessert topping, but the Tesla Motors Lithium-Ion cells are not classified as hazardous and are landfill safe. However, dumping them in the trash would be throwing money away, since the battery pack can be sold to recycling companies (unsubsidized) at the end of its greater than 100,000-mile design life. Moreover, the battery isn't dead at that point, it just has less range.

POWER PLANT EMISSIONS AKA "THE LONG TAILPIPE"


(For a more detailed version of this argument, please see the white paper written by Martin and Marc.)

A common rebuttal to electric vehicles as a solution to carbon emissions is that they simply transfer the CO2 emissions to the power plant. The obvious counter is that one can develop grid electric power from a variety of means, many of which, like hydro, wind, geothermal, nuclear, solar, etc. involve no CO2 emissions. However, let's assume for the moment that the electricity is generated from a hydrocarbon source like natural gas, the most popular fuel for new US power plants in recent years.

The H-System Combined Cycle Generator from General Electric is 60% efficient in turning natural gas into electricity. "Combined Cycle" is where the natural gas is burned to generate electricity and then the waste heat is used to create steam that powers a second generator. Natural gas recovery is 97.5% efficient, processing is also 97.5% efficient and then transmission efficiency over the electric grid is 92% on average. This gives us a well-to-electric-outlet efficiency of 97.5% x 97.5% x 60% x 92% = 52.5%.

Despite a body shape, tires and gearing aimed at high performance rather than peak efficiency, the Tesla Roadster requires 0.4 MJ per kilometer or, stated another way, will travel 2.53 km per mega-joule of electricity. The full cycle charge and discharge efficiency of the Tesla Roadster is 86%, which means that for every 100 MJ of electricity used to charge the battery, about 86 MJ reaches the motor.

Bringing the math together, we get the final figure of merit of 2.53 km/MJ x 86% x 52.5% = 1.14 km/MJ. Let's compare that to the Prius and a few other options normally considered energy efficient.

The fully considered well-to-wheel efficiency of a gasoline powered car is equal to the energy content of gasoline (34.3 MJ/liter) minus the refinement & transportation losses (18.3%), multiplied by the miles per gallon or km per liter. The Prius at an EPA rated 55 mpg therefore has an energy efficiency of 0.56 km/MJ. This is actually an excellent number compared with a "normal" car like the Toyota Camry at 0.28 km/MJ.

Note the term hybrid as applied to cars currently on the road is a misnomer. They are really just gasoline powered cars with a little battery assistance and, unless you are one of the handful who have an aftermarket hack, the little battery has to be charged from the gasoline engine. Therefore, they can be considered simply as slightly more efficient gasoline powered cars. If the EPA certified mileage is 55 mpg, then it is indistinguishable from a non-hybrid that achieves 55 mpg. As a friend of mine says, a world 100% full of Prius drivers is still 100% addicted to oil.

The CO2 content of any given source fuel is well understood. Natural gas is 14.4 grams of carbon per mega-joule and oil is 19.9 grams of carbon per mega-joule. Applying those carbon content levels to the vehicle efficiencies, including as a reference the Honda combusted natural gas and Honda fuel cell natural gas vehicles, the hands down winner is pure electric:

CAR



ENERGY SOURCE



CO2 CONTENT



EFFICIENCY



CO2 EMISSIONS


Honda CNG

Natural Gas


14.4 g/MJ

0.32 km/MJ

45.0 g/km

Honda FCX


Nat Gas-Fuel Cell

14.4 g/MJ

0.35 km/MJ

41.1 g/km

Toyota Prius


Oil

19.9 g/MJ

0.56 km/MJ

35.8 g/km

Tesla Roadster


Nat Gas-Electric

14.4 g/MJ

1.14 km/MJ

12.6 g/km

The Tesla Roadster still wins by a hefty margin if you assume the average CO2 per joule of US power production. The higher CO2 content of coal compared to natural gas is offset by the negligible CO2 content of hydro, nuclear, geothermal, wind, solar, etc. The exact power production mixture varies from one part of the country to another and is changing over time, so natural gas is used here as a fixed yardstick.

BECOMING ENERGY POSITIVE


I should mention that Tesla Motors will be co-marketing sustainable energy products from other companies along with the car. For example, among other choices, we will be offering a modestly sized and priced solar panel from SolarCity, a photovoltaics company (where I am also the principal financier). This system can be installed on your roof in an out of the way location, because of its small size, or set up as a carport and will generate about 50 miles per day of electricity.

If you travel less than 350 miles per week, you will therefore be "energy positive" with respect to your personal transportation. This is a step beyond conserving or even nullifying your use of energy for transport - you will actually be putting more energy back into the system than you consume in transportation! SO, IN SHORT, THE MASTER PLAN IS:

* Build sports car


* Use that money to build an affordable car

* Use "that" money to build an even more affordable car


* While doing above, also provide zero emission electric power generation options

Don't tell anyone.
