where electricity is not available

Combination of renewable source of energy such as wind/solar with diesel generator appears to find increasing appeal in implementing decentralized electricity generations system for remote places of Nepal. The addition of diesel generator to the renewable source of energy provides power on demand, improves reliability and reduces the initial cost of the hybrid plant. Similarly, renewable source of energy addition to a conventional fossil fuel operating diesel generator reduces fuel consumption, thus improving the economics and environmental attributes of the power source. This system can be applied to various geographical conditions, mountain hills, island, plain areas or remote areas, where electricity is not available.

A review of the overall energy production and utilization as well as the system performance of Wind and Solar PV hybrid system in Nepal indicates the promising potential of such system in the coming days.

California — A new government study shows that Americans are using less energy overall and making more use of renewable energy resources.

The United States used significantly less coal and petroleum in 2009 than in 2008, and significantly more wind power. There also was a decline in natural gas use and increases in solar, hydro and geothermal power according to the most recent energy flow charts released by the Lawrence Livermore National Laboratory(www.llnl.gov).

“Energy use tends to follow the level of economic activity, and that level declined last year. At the same time, higher efficiency appliances and vehicles reduced energy use even further,” said A.J. Simon, an LLNL energy systems analyst who develops the energy flow charts using data provided by the Department of Energy’s Energy Information Administration. “As a result, people and businesses are using less energy in general.”

The estimated U.S. energy use in 2009 equaled 94.6 quadrillion BTUs (“quads”), down from 99.2 quadrillion BTUs in 2008. (A BTU or British Thermal Unit is a unit of measurement for energy, and is equivalent to about 1.055 kilojoules). The average American household uses about 95 million BTU per year.

Energy use in the residential, commercial, industrial and transportation arenas all declined by .22, .09, 2.16 and .88 quads, respectively.

Wind power increased dramatically in 2009 to.70 quads of primary energy compared to .51 in 2008. Most of that energy is tied directly to electricity generation and thus helps decrease the use of coal for electricity production.

“The increase in renewables is a really good story, especially in the wind arena,” Simon said. “It’s a result of very good incentives and technological advancements. In 2009, the technology got better and the incentives remained relatively stable. The investments put in place for wind in previous years came online in 2009. Even better, there are more projects in the pipeline for 2010 and beyond.”

The significant decrease in coal used to produce electricity can be attributed to three factors: overall lower electricity demand, a fuel shift to natural gas, and an offset created by more wind power production, according to Simon.

Nuclear energy use remained relatively flat in 2009. No new plants were added or taken offline in this interval, and the existing fleet operated slightly less than in 2008.

Of the 94.6 quads consumed, only 39.97 ended up as energy services. Energy services, such as lighting and machinery output, are harder to estimate than fuel consumption, Simon said.

The ratio of energy services to the total amount of energy used is a measure of the country’s energy efficiency.

Carbon emissions data are expected to be released later this year, but Simon suspects they will tell a similar story.

“The reduction in the use of natural gas, coal and petroleum is commensurate with a reduction in carbon emissions,” he said. “Simply said, people are doing less stuff. Therefore, they’re burning less fuel.”

SCENARIO OF NEPAL

Nepal is facing problems in electricity production resulting to an everyday crisis of load shedding. It has created a disturbance and has widely affected the living condition of the people. This outrages the demand for energy, either by import or by availability from the nation itself. The implementation of the country’s own indigenous material and technology in the production of alternative sources of energy is the best way to uplift the rapid growth, need and requirement fulfillment. In case of a developing country, the use of national renewable resource could be a step towards development. The renewable resources such as solar and wind power are certain to assist the country in the case of precise documentation. This initiation is set to help Alternative Energy Promotion Center (AEPC), Ministry of Environment (www.aepc.gov.np) in their venture towards the generation of power from alternative sources of energy. It ensures positive prospects for the country’s sustainable future.

This study focuses on the implementation of the renewable sources of energy such as wind and solar. The documentation of wind data in many areas of Nepal can be an important step forward for the implementation of power in the form of electricity. The feasibility and the cost of any project from production to generation and implementation level cannot be acquired without it. Therefore data collection is the first and the foremost requirement.

In recent years, continuous effort in wind data collection is done mostly by foreign expertise. There is still lack of data and weak research study creating voids tending to impede the flow. The budget is not yet categorized for wind data measurement, required efficiency and exact analysis. A database will eventually fulfill the primary need to an extent.

China doubles installed capacity for fifth year running – Global markets up 31%

Brussels, February 03, 2010. The Global Wind Energy Council today announced that the world’s wind power capacity grew by 31% in 2009, adding 37.5 GW to bring total installations up to 157.9 GW. A third of these additions were made in China, which experienced yet another year of over 100% growth.

“The continued rapid growth of wind power despite the financial crisis and economic downturn is testament to the inherent attractiveness of the technology, which is clean, reliable and quick to install. Wind power has become the power technology of choice a growing number of countries around the world,” said Steve Sawyer, GWEC’s Secretary General. “Copenhagen didn’t bring us any closer to a global price on carbon, but wind energy continued to grow due to national energy policy in our main markets and also because many governments in prioritised renewable energy development in their economic recovery plans,” he said.

Wind energy is now an important player in the world’s energy markets. The global wind market for turbine installations in 2009 was worth about 45 bn EUR or 63 bn US$. GWEC estimates that around half a million people are now employed by the wind industry around the world.

The main markets driving this significant growth continue to be Asia, North America and Europe, each of which installed more than 10 GW of new wind capacity in 2009.

China was the world’s largest market in 2009, nearly doubling its wind generation capacity from 12.1 GW in 2008 to 25.1 GW at the end of 2009 with new capacity additions of 13 GW.

“The Chinese government is taking very seriously its responsibility to limit CO2 emissions while providing energy for its growing economy. China is putting strong efforts into developing the country’s tremendous wind resource. Given the current growth rates, it can be expected that the even the unofficial target of 150 GW will be met well ahead of 2020,” said Li Junfeng, Secretary General of the Chinese Renewable Energy Industries Association.

Newly added capacity of 1,270 MW in India and some smaller additions in Japan, South Korea and Taiwan make Asia the biggest regional market for wind energy in 2009, with more than 14 GW of new capacity.

However, the US continues to have a comfortable lead in terms of total installed capacity. Against all expectations, the US wind energy market installed nearly 10 GW in 2009, increasing the country’s installed capacity by 39% and bringing the total installed, grid-connected capacity to 35 GW. In early 2009, some analysts had foreseen a drop in wind power development of as much as 50%, but the implementation of the US Recovery Act with its strong focus on wind energy development in the summer reversed this trend.

“The U.S. wind energy industry shattered all installation records in 2009, chalking up the Recovery Act as a historic success in creating jobs, avoiding carbon, and protecting consumers,” said AWEA CEO Denise Bode. “But U.S. wind turbine manufacturing is down compared to last year’s levels, and needs long-term policy certainty and market pull in order to grow.”

Europe, which has traditionally been the world’s largest market for wind energy development, continued to see strong growth, also exceeding expectations. In 2009, 10.5 GW were installed in Europe, led by Spain (2.5GW) and Germany (1.9 GW). Italy, France and the UK all added more than 1 GW of new wind capacity each.

“It is a remarkable result in a difficult year” said Christian Kjaer, CEO of the European Wind Energy Association. “The figures, once again, confirm that wind power, together with other renewable energy technologies and a shift from coal to gas, are delivering massive European carbon reductions, while creating much needed economic activity and new jobs for Europe’s citizens.”

“Wind energy is already making a significant contribution to saving CO2 emissions. The 158GW of global wind capacity in place at the end of 2009 will produce 340 TWh of clean electricity and save 204 million tons of CO2 every year,” concluded Sawyer. “As we see in Europe and the US, wind power is now often the most attractive option for new power generation, both in economic and environmental terms, and for improved supply security.”

Mustang District is one of the favourite tourist destination of Nepal. So the demand of electricity for this region is very high. People in this area still depend upon traditional energy resources; such as firewood kerosene and other petroleum products to fulfill the energy demand except in some potential places where solar and micro hydropower in use for the lightning purposes. In this context it should be noted that Mustang is one of the high wind energy potential areas of Nepal.

Based on the wind data of Mustang district collected by AEPC, the wind velocity at hub height of 20 m was recorded as 75 m/s at maximum. This is the highest wind velocity recorded at any place in Nepal till date. According to the SWERA (Solar and Wind Energy Resource Assessment in Nepal) report prepared by AEPC, the annual average wind power density (WPD) of Mustang District is 332 watt/m2. Wind power density less than or equal to 100 Watt/m2 are not useful for wind energy harnessing. WPD greater than 200 Watt/m2 are normally taken for consideration for non grid connected power generation while greater than 300 Watt/m2 are considered as grid connectivity wind energy in developing countries. The analysis shows area above 300 Watt/m2 composed of 30 sq km and with 5 MW installed per sq km, yields 150 MW.

These areas have been calculated on a conservative basis so that the exploitable area for wind energy can be increased by covering greater area from the national grid and especially analyzed in specific areas with greater wind energy potential.

Studies have shown that there is high potential for wind power generation in the Mustang district, small wind turbine systems of 1500 watt could be easily installed to electrify the area without long-term data. Wind Power System would help in conservation of environment and forest by reducing carbon emissions thereby making the area pollution free. Wind energy can be used to provide electricity for the people and Mustang would be a model village that uses sustainable power generation through wind energy.
