driven by oil, coal and natural gas conventional fossil energy supply tightens, the biological energy with its renewable charater gets more and more social attention. From Jatropha as raw material for the biodiesel development to the straw direct combustion of generate electricity, to the use of waste oil, Yunnan has done a very good attempt and exploration. Bio-energy exploration in Yunnan has made new achievements, Kunming institute of electrical energy company research and develop a new biomass carbonization cracking technology, created out of a new world of bio-energy use, which adapt the yunnan this a big agricultural province straw rich but relative to the actual raw materials, and scattered by the attention of capital.And traditional biomass energy use is not the same, electric research new energy mainly research and development of biomass gasification power generation, gasification gas, direct-fired heating,gasification of biomass briquette and ecological agriculture, forestry, waste of utilization. “The technology more adjust to actual yunnan, which can reduce the transport costs of straw.” The new energy, chairman of the board of inquiry CaiZheng introduction, now the mainstream minimum straw burning power of installed generation is difficult to adapt to the yunnan scattered straw raw material supply reality, the inadequate supply of straw will lead to direct combustion power generation of the radiation radius of raw materials is too broad, Leading an increase in freight straw, thereby greatly increasing the cost of straw direct combustion power generation, which has become a straw burning power constraints. The electricity research new energy through the control warm solution technology, The agricultural straw, forestry litter biomass raw materials transform into gas fuel, for direct heating and power generation, and access to high quality biomass carbon used in industrial silicon and nonferrous metallurgy industry. Yunnan is a major agricultural province, there are plenty of straw and tobacco stalks. The information provided by the provincial development and reform committee,Yunnan has 4.14 million hectares of used cultivated land, accounting for 10.5% of total land area, the total sown area of 6.0536 million hectares, cropping up 146.22%, major crops straw yield can reach 22.374 million tons. It is estimated that the province’s agricultural production each year can produce about 25 million tons of straw,adding the forestry waste and growing economic forest every year,which an annual source of biomass as a raw material is abundant. But yunnan straw raw materials more decentralized, together with straw origin is mainly mountainous area, straw transportation is a big problem, so how to reduce the radius of the collection of straw, biomass energy is to reduce the cost of a key. The research of the development of new energy biomass’s density molding equipment straw radiation radius is 10 kilometers, the cost of biomass can reduce a lot. Yunnan rich straw resource completely satisfy small biomass gasification occurrence boiler material of requirements, Therefore, promote the use of biomass energy molding density equipment not only can change the peasants for thousands of years to direct firewood for cooking, heating and backward way of life, leting farmers use their convenient, clean, economical gas, but also more conducive to promoting the urbanization of rural development goals. With this product miniaturization and cost-effective, meet the demands of life of rural customers and market demand.

“We can create a more sustainable, cleaner and safer world by making wiser energy choices”. ~ Robert AlanThe professor was touring villages in Karnataka, gathering information for a program called Sustainable Transformation of Rural Areas. Soil and growing conditions were harsh in much of the area, and many of the villages were poor.

In one such village, the professor and his team of research assistants stopped in a tea stall. Naturally, the strangers drew attention in the small village. One villager struck up a conversation with the professor, and asked what the visitors were doing.

“We’re looking for ways to use science and engineering principles to solve real-life problems in villages like this one”, Professor Shrinivasa told the man. The villager thought for a moment. “Well, we use oil from the Honge tree to light the lamps in our temples”, the man volunteered. “Maybe you could find some other use for that oil”.Indeed he could. The professor, who is based at the Indian Institute of Science, found that the Honge tree (whose Latin name is Pongamia Pinnata) grew throughout the village, and oil could easily be extracted from the tree’s plentiful pods.

He also recalled that many years ago Rudolf Diesel had used peanut oil when demonstrating his invention, the diesel engine. The professor told his colleagues, “Let’s try this oil in a diesel engine right here in the village”.

They got some oil, borrowed a small diesel engine, started it up and – boom! – the engine fired up, ran smoothly and kept running smoothly. Villagers immediately began using the local oil instead of spending money to buy diesel fuel.That was a decade ago, and since then Professor Shrinivasa has traveled to relatively less fertile lands across India to promote the planting of Pongamia trees as a source of alternate fuel.My wife Girija and I met Professor Shrinivasa recently, and found that he had lost no passion for his cause. He talked enthusiastically about the benefits of Pongamia-based bio-diesel. For one, it is grown in dry lands and hence does not lead to the food shortages sometimes caused when farmers grow corn or soya for bio-fuel instead of other crops for food.

Second, in terms of emissions, bio-diesels are carbon neutral: the carbon dioxide absorbed by the trees is released when the fuel is burnt. Third, in terms of particles that cause pollution and respiratory diseases, bio-diesel emissions are less harmful than petrol and diesel.

The economics are compelling. A hectare of wasteland growing Pongamia trees can yield 10 tonnes of seeds worth around Rs. 40,000. Horticulture is far less labor intensive and hence can be done at relatively low costs, providing a good return to the farmers.

The professor’s calculations show that India has adequate availability of wastelands that can be planted with enough Pongamia trees to meet the entire nation’s petrol and diesel requirements.

But this calls for enormous political will and an ability to overcome the petroleum lobbies. As a lone champion, Professor Shrinivasa has yet to build the momentum to battle these forces – but continues on his path regardless.

The Connected Age requires us to look for viable alternatives in various aspects of our daily lives. It requires us the boldly embrace these new alternatives – as they emerge.

It requires us to battle the vested interests and the entrenched beliefs of the industrial age with the vision of creating a more inclusive and sustainable world. And it requires us to step forward the way the professor has, and to support people like him who have stepped forward. Do share your own insights in this area.

Released in November this year the Danish government’s energy development plan show that by 2050 the entire transport system will be completely dependent on renewable energy. Danish Government’s long term goal is to completely use of electric vehicles, and short-term solution is 10% of transport energy come from biofuels in 2020. Large-scale use and promotion of biofuels this approach raises a number of academics and non-governmental organizations questioned.Danish Institute of International Studies PhD stew WenDiMu method, plug in the 7 th institute web site to comment on the article “biofuels whether can realize his promise?” Questioned this practice. According to the article, bio-fuels as an alternative to fossil fuel energy, wide attention in the international community. On the one hand, compared with fossil fuels, biofuels is more efficient cleaner, can significantly reduce carbon dioxide and other greenhouse gas emissions, The other hand, the main source of bio-fuels from rural areas, development of bio-fuels can promote rural economic development. However, the article pointed out that the latest scientific research shows that biofuels cause greenhouse gas emissions is more than previously imagined and actually clean energy is not “clean.”In addition, large-scale use of bio-fuels contribute to the international food prices, which in 2007 and especially 2008. Limited agricultural land in developing countries, while developed countries constantly increasing demand for biofuels will lead to developing countries used the land to grow biofuel crops, causing food land shortages and thus promote soaring food prices.The article points out, developing countries used to grow biofuel crops of the land area is 500 million hectares, and if the entire European Union to achieve 10% of the transport energy from biofuels, the need of the land area is 500 million hectares.The article points out, ready to deal with these shock, and the reasonable control of biofuels industry investment, these countries will cause the interests of vulnerable groups further damage and deterioration, poverty level will continue to intensify. Depletion of fossil fuels for the current situation, development and utilization of new renewable resources such as biomass it is a priority, but we must do the detailed planning to ensure that the development of new energy at the same time, Wwll not hurt the interests of other. Development of biomass energy has always been the original intention of the sustained and healthy development for the world, and if such damage to the food, or the interests of the people will lead to other disadvantages, so our efforts in vain, and even lead to the greater disaster.

A few years ago, renewable energy was not getting people’s attention. But for the past two years, non-renewable energy was not steadily supplied and the oil price keeps rising up. Energy issues become to constrain national’s economic development. In response to high oil prices, countries around the world launched a new energy strategy, which is to seek for a new driving force for economic development. Therefore, the renewable energy like bio-energy, solar energy, wind energy and other new energy products are being developed by all countries. Even though the renewable energy development has a bright future, it also has to face some challenges.

The shortage of silicon is restricting the development of solar energy industry.

As the best energy in all new energy industry, solar energy is being developed by all counties.On August 18th, Australia Queensland governor was in one solar plant in Nevada. He said they will establish cooperation relationship with Nevada. Queensland will build a solar industry park to reduce Queensland’s dependence on coal-fired power generation. Not long time ago, the Israeli electricity management department pronounce: From July, People who install the solar power electricity system can sell their surplus electricity to National Grid for approx us0.6/W

It will cost about us$ 8,800 to in stall a solar electricity system that has 10kilowatts’s generating capacity. In this way, if people sell the electricity to National Grid, they will be able to pay off the system for less than 10 years. At the same time, Israeli public authority will offer solar security systems for solar power equipment to support private solar electricity system’s installation.

Samsung Economic Research Institute predict that the money in the world solar power market will increase from 15 billion us dollar in 2005 to 36.1 billion us dollar in 2010.In South Korea, the 2007 domestic solar power generation capacity is about 44 megawatts. This year, it is expected to go up to 100 megawatts. It will increase to 4000 megawatts by 2010.

But in fact, all the solar energy companies are facing tough cost challenges. Along with the rapid development of industry, silicon price is rising up crazily. According to the data, it was US 300 dollar per kilogram on 2006.But in 2007, it comes up to us 400 dollar per kilogram. With the rapid expansion of domestic energy industry, the silicon price will keep going up. The cost of solar energy panel will also be greatly raised!

Experts say that one watt electricity from solar system’s cost is about 0.6 us dollar.And the fuel generation cost is less than 0.2us dollar. Since the silicon price is so high, the solar power cost will be more than 0.6 us dollar. Somebody predicted that oil price will go up to 200 U.S. dollars per barrel, and oil power generation cost will be about 0.4 us dollar. Solar power cost is still higher than the cost of fuel power generation.

In conclusion, while we are developing our economy, we should pay attention to protect our environment! Governments should support the renewable energy industry’s development by all means! So that we can live on a nice earth!
