Wind Vs. Solar in the Race for India’s Energy Future This article compares the present and future potential for energy production from wind and solar sources in India and presents a brief analysis of future trends in these two energy technologies. Introduction India is undergoing an energy crisis. 53% of the country’s current power needs come from coal. This highly polluting source of energy is bound to run out someday. Compared to the West, India’s energy consumption is growing at break-neck speed. As India’s poor millions advance out of poverty, they are consuming more and more power, outstripping national power production.

The negative gap between consumption and production has been increasing exponentially in the past two decades, forcing the government to buy increasing quantities of power from abroad. This trend is set to continue, with the country doubling it’s energy consumption in the next 20 years. Finding alternatives to fossil fuel-based energy sources is vital to India’s future if it wants to continue sustained growth. Careful analysis of future trends is important for providing the right information to companies wanting to get involved in energy production.

Since wind and solar energy sources are widely popular and considered to be important in India’s development of renewable energy (RE) ,an important place to begin the analysis is by studying the inherent potential for these two energy sources. In this article I will limit my analysis of the RE sector to these two energy sources. Wind potential: Currently, India is fifth in the world in terms of installed wind power capacity. It is second, only after Germany, in the rate of growth of it’s wind sector. Wind power accounts for 6% of the total installed power capacity and 1. 6% of the actual power production in India.

The total wind energy potential in India is 10 times the total installed capacity. Given these figures, it is no surprise that this source for energy production has received much attention in the past few years. The major benefits of wind power are it’s fast set-up and turnover, clean environmental record, low operating and maintenance costs, relatively low capital costs and operation without the need for high-tech equipment. These are immediately recognized as ideal conditions for any seeking a quick business solution. However, wind also comes with it’s unique disadvantages.

The most prominent of these is the fact that wind patterns vary seasonally and geographically. This means that it can only be tapped to make electricity in some localized parts of the country, and the electricity production will vary throughout the year. The map on the right shows how just a few regions of the country are suitable for wind power harvesting. The wind patterns in India have been mapped and the areas with highest wind energy potential have been identified: For those parts of the country without sustained strong winds, wind power may not be the best answer.

Solar potential: Compared to wind, India lags behind in solar power production. Only about 0. 5% of the country’s power comes from solar. This is despite the availability of plenty of solar radiation in most of the country. In fact, India is one of the best places in the world to develop solar solutions for energy. Compared to wind, solar radiation is a much more abundant resource in India. Insolation levels are high all over the country, allowing for de-centralized, off-grid approaches to power production.

Not only does this lead to a more stable system (because of less risk of any large scale power outages), but it is extremely efficient in terms of land area used (rooftops and open terraces can become energy sinks) as well as in terms of energy conservation (because inefficient, expensive and long transmission lines can be avoided). The map on the left shows how India receives an average of over 5. 6 Kilowatts /Sq. meter every day. There are some disadvantages, however. Unlike wind, solar energy cannot be harvested at night. In India, an average of 65 days of the year are overcast and radiation levels are low on those days.

Even after taking into consideration these problems, solar power still remains a much better solution to India’s energy problems in terms of total energy potential. But there is a practical technology issue that is preventing more widespread adoption of solar solutions in India. The capital needed to set up solar electric systems is really high. Currently, the electricity obtained from a solar installation costs between 6 and 10 times that obtained from conventional coal based sources. Trends in technology: Today, the focus of the renewable energy industry in India has been on wind. Solar has received much less attention.

The reason why this discrepancy between solar and wind based energy production is seen in India is the high cost of solar technology installations, both photo-voltaic and solar thermal, compared to wind technology installations. Solar photo-voltaic technology is becoming more efficient by the day. Newer and cheaper methods of producing the silicon wafers needed to make the photo-voltaic sheets used in solar installations are being created. There have been major breakthroughs in both amorphous and crystelline silicon sheets. In the US and in Europe, scientists have developed higher efficiency levels than ever before.

Today, solar paint, solar pavements, solar sheets and solar fabric have been produced. This is just the beginning in exploring the adaptability of solar cells in outdoor human activities. We may be reaching a physical limit in the efficiency of solar cells, but the cost of making these cells will come down if there is sufficient investment in this area. The reason why business and government have focused mostly on wind and not so much on solar alternatives, is because of a lack of foresight combined with a desire for fast solutions. Wind power is already an attainable goal for India.

The promise of quick economic gains is the incentive behind the recent growth in the wind sector. Investors have flooded money into the market and today the industry is spending a lot of money on increasing the total capacity, while not following through on the production. This indicates a lack of foresight in considering the limitations of wind power. The government has responded by providing incentives for the wind industry to invest more into this energy alternative, while not recognizing the need for incentives for solar that could help to develop cost-effective solar power installations.

There is no doubt that wind will continue to grow, but the current model of development is more hype than substance. The future must see a shift in this trend. Consider and compare India’s solar and wind potential in the world stage: It is clear that when the technology becomes available, solar will provide a much more reliable and productive source of power for India. This analysis concludes that for a stable energy future based on wind and solar, a balanced approach in policy and business is necessary.

On the short term, we need to focus on utilizing the wind power capacity we already have installed while encouraging companies to invest wisely in wind power. Meanwhile, a long-term strategy must seriously promote the potential for solar power in India. Investors in RE must take a long term view of solar power. The same goes for government. If too much government incentive is focused on wind and development of solar alternatives is shelved, we will have a lot of catching up to do when our demand for power becomes too high to be supported by the dwindling supply of fossil fuels.
