Now NY goes solar : From small steps to giant leaps

Our View:

NY has now expressed its intent to join the U.S. Solar club. Egged on by the Governor’s rather ambitious 45-15 renewable energy program, the Long Island Power Authority and NYPA have moved ahead to propose two medium sized photovoltaic module solar plants of 50 MW and 100 MW at Long island and New York . NY follows early leaders like California and Arizona who have already moved forward with large Solar Projects powered by both CSP and PV Technologies. New York’s entry into the solar energy arena shows that U.S. is now gearing itself to seriously challenge the early leadership of EU members Spain, Germany and Portugal and will not limit its solar ambitions to the sun baked desert states of the south.

These are early days for solar energy. Years of back breaking development exercise saw rising costs of manufacture and hundreds of early entrants go bust. Unresponsive Financial Institutions, Banks and Governments, stifled the flow of easy credit and refinance to this fledgling industry causing many a development projects to stop half way. It was also haunted by wrangling and dispute on the technology path to be adopted for getting the best results at the lowest cost. The cheaper price of fossil fuel and intense global competition in almost all energy user industry segments added to woes of the solar power industry. Their cause was further damaged by a covert global campaign nurtured by the oil and coal producers pumping in millions of Dollars as lobbying, campaign and media contributions to show the world that renewable energy was not a feasible alternative for the worlds energy needs. All these helped delay the growth of this infant industry that took a record 40 years to grow from the drawing board to the commercial application stage. Small developments in the sun bathed European states of Spain, Germany and California in the US were taking place during this period, but nothing to evoke a worldwide interest

A 2004 ministerial ruling in Spain , the Royal decree 436, changed the course of events dramatically. Sensing the unique benefits that Solar energy can give to this sunshine state that must import all its oil, the Government against advice of the EU, World Bank and other financial advisors established a lifelong subsidy scheme for the early solar projects. It created two alternative payment schemes, both guaranteed over the 25 year life-cycle of thermal solar plants, and diminishing thereafter. The first is a fixed, guaranteed payment of 300% of the Average Reference Tariff (ART) for electricity. The second induces operators to compete on the national wholesale electricity market, where the generating company received 250 % of the ART plus a 10 % additional incentive.

Of the three main technologies that have moved ahead in the field of Solar energy are the CSP or the Concentrated Solar Power projects using the Tower Technology with hellostat reflectors at the ground level , the CSP using the Tower mounted giant parabolic troughs and the PV or the Photovoltaic Cell based Projects. Abengoa a Spanish manufacturer which produces all three versions moved ahead with the world’s first commercial project using both versions of the CSP Technology having a net proposed combined capacity of 300 MW.

The first of the CSP units was the hellostat version commissioned in March 2007 in Seville having an installed capacity of 11 MW and the other projects are in construction to ensure that the 300 MW solar farm is commissioned by 2013. Abengoa has also signed a contract with Arizona Public Service APS in the U.S. to put up a 280 MW CSP project with parabolic troughs and storage in Phoenix. Besides other Spanish players like turnkey contractor ACS Cobra and utility company Iberdola are not far behind with their solar projects as a result of which Spain should witness an installed capacity of 1000 MW before 2013 . Portugal, and Germany also were not far behind with the first solar farms with PV technology the 11 MW Serpa Project with 520,000 PV modules to provide electricity to around 8000 homes, commissioned in early 2007. They were followed by the 46 MW Moura photovoltaic power project in Portugal, and the 40 MW Waldpolenz Solar Park in Germany in quick succession.


Not to be outdone by the early European lead in the field of solar energy the California Energy Commission a world leader in energy efficiency and conservation , took giant strides towards solar based projects by announcing its intention to set up 3000 MW solar facility in the state by 2016 .The Pacific Gas & Electric Company the largest Utility Company in the state quickly moved in to sign two separate contracts of Photovoltaic Solar Projects with Optisolar and Sunpower Inc. In August 2008 PG&E entered into an agreement with Topaz Solar Farms LLC, a subsidiary of OptiSolar Inc., for 550 MW of thin-film PV solar power. The utility also signed a contract with High Plains Ranch II, LLC, a subsidiary of SunPower Corporation (Nasdaq: SPWR), for 250 MW of high-efficiency crystalline PV solar power projects. Though the cost of both projects was kept under wraps, it was understood that the Optisolar project based on mass production technologies would bring down solar energy costs substantially. The September Global financial meltdown however took its toll on the Optisolar, a Calfornia based start-up. As the credit crunch hit the markets the company failed to raise more than $ 200 million for the project. This was unfortunately less than a third of the first flush of funds required to set up the farm. Optisolar thus sold out its lucrative contracts to its competitor the bigger and well established First Solar a publicly held company that also specialised in thin film semiconductor technology and could make good use of its mass production techniques to cut costs.

First Solar, the biggest U.S. player in the Solar Energy with PV Technology claims to have brought down its cost of manufacture of its solar modules from a high $ 3 per watt in 2004 to just 98 cents per watt during the 1st Quarter of 2009 . This will undoubtedly have great impact on Solar power whose generation cost today is $ 6000 per MW against $ 2000 per MW of the coal based thermal plants. With more solar plants on the anvil, and competition and collaboration across Europe and U.S. beginning take shape, the prices of both manufacture of modules and installation of Solar plants are bound to drop sharply. European manufacturers have also tied up with Indian & Chinese companies to produce PV modules which will further lead to cost cutting. Besides demand from India and China can be huge as both these nations are short of energy required to meet their high 7% plus annual growth patterns. If this happens it will be the best thing for the solar power industry which can derive benefits from the economies of scale and become a true competitor that can match fossil fuel plants without Government subsidies or incentives .

In this blog from “ecology to economy” we deal with discussion of sustainable practices which we must adopt for the for various aspects of economy as well as climate change. We are focusing in this issue on the latest developments in the Solar energy industry and the real implications it will have on climate change and the international economy.

Buffet invests in "solar energy". Shows it has arrived.

Our View:
Investment wizard Warren Buffet has taken 10 % stake in a little known Chinese solar energy equipment manufacturer BYD with a turnover of around 3 billion USD. A supplier of mobile phone batteries and handsets to Motorola, Nokia, Sony Ericsson and Samsung, this 15 year old company diversified into automobiles by buying a sick state run automobile in 2003. In less than 5 years the BYD sedan called F3 outsold illustrious brands like Toyota Corolla, and Volkswagen in the Chinese market attracting the attention of Buffet's Berkshire Hathway investments.
BYD has also introduced a plug-in electric car F3 DM with a backup gasoline engine, that runs 62 miles on a single solar charge, a move that puts it ahead of GM, Nissan, and Toyota. Besides it is entering the US market with a new product called “ The home clean power solution” which are essentially solar photovoltaic roof top panels with built in batteries to store solar energy for use when the sun is not out. The dynamic moves by this Chinese manufacturer proves that for ecology to be acceptable it must blend into the economy as a cost effective solution.
Warren Buffet famous for his conservative and failsafe rules of investment had once stated “ never invest in a business you do not understand.” He stayed away from the tech boom of the eighties that saw thousands of dot com companies raise billions of dollars from investors, and venture capitalists only to crash a few years later. He was critical of the derivatives industry which he famously named “ the financial weapons of mass destruction” and invested only with Banks like Wells Fargo and American Express who stayed away from the toxic sub-prime mortgages. Though these toxic mortgages repackaged as derivatives surged initially, the housing prices crashed a few years later sending stalwarts of the Wall Street like Lehman Brothers, Citi, AIG running for cover, while Wells Fargo posted record profits.
Buffets investment in a solar energy major gives the indication that solar energy has indeed arrived. We are sure that the decade 2010-2020 will see it forge ahead of fossil fuel and make it the cheapest and most favoured energy source on earth.
At the Blog Economy to Ecology we salute the progress of this small but dynamic solar energy company which promises to get into big league tomorrow.

Solar energy is the solution for a Carbon free world

Our view :


This is a new series we are begining.
It deals both with economics and climate change.
It is on the economics of solar energy.
Its future as the alternative to fossil fuel & nuclear energy.

We believe it can happen.
We are seeing and feeling it happening.
The process has begun.
A lot of hard work has been done.
Medium size capacities from 300 to 500 MW solar energy units are today being set up.
Only the scaling up of capacities remains to be done.

This must attain momentum.
The economics and volumes must grow quickly, to make it cheaper .
We must reach the critical point....... and quickly
We must scuttle the efforts of the conventional energy producers to confuse the issues,
term it as costly, a expensive proto type...... still on the drawing board
and hog the funding and blessings of our powerful governments
and eventually divert it to other alternatives....
like CCS, the Carbon Capture & Storage technology,
that is even mischievously called it the Clean Coal Technology

So as we begin this argument we call it " a concept paper "

This is a the begining of a long series of arguments that will take more than 20 posting.
We invite the fossil fuel and other lobbies to enter the discussion if they wish.
Show us why the world governments must go for expensive Clean coal CCS technology.
Why expensive resources must be put in solutions which cannot be mass produced,
within the available global resource base and energy requirements.

To start our dicussion we go back 40 years from where the analytics of climate change began.
The analytics of climate change began with a debate among environmentalists to measure and quantify the effect of climate change in the seventies. American ecologists Paul Ehrlich and John Holdren who created the first mathematical concepts that equated human consumption
to climate change called it the IPAT equation. The equation basically is an easily understood thumbrule for the common man , that relates the impact of consumption to human growth

The equation was I = PAT

where I is the Impact of human activity is a product of P x A x T

where P is the Population of the world (currently 7 billion)

A is the level of affluence, that is the per capita GDP of this world population. ( currently $ 8000)

T is the technology or the carbon emission effect of technology in producing energy.
(currently 0.5 Tonnes of CO2 per $ 1000 of resources consumed )

Using this simplistic equation we find I = 7 billion x 8 x 0.5 = 28 billion Tonnes of Co2

The safe limit as per the IPCC (Intergovernmental Panel on Climate Change) is only 5 billion tonnes of Co2 emission , or 450 parts per million carbon content by 2050

How to achieve this?

By reducing population ....... highly unlikely

By reducing consumption...... difficult as politicians adore the economics of growth

By improving technology...... Yes, but only if we choose correctly and move quickly.

What is the correct technology or technologies to choose ?

In our next posting we shall try to simplify and explain the relevant technologies & the economics of viability, profitibilty and control dynamics in the global energy markets.
