中国有广大的约占国土面积40 %的沙化退化草原，不宜亦没有用作粮食耕地。但经过大力的生态建设后每年能产出巨量的巨银草。后者是原生在中国北部，能耐干寒和恶劣环境，并是多年生高达3.5 m的巨大稠密的野草，并能利用咸水。将这些巨银草气化催化后估计每公顷可产出17.2 t的可直接替代汽油的生物丁醇，生化和基因研发专业公司孟山都和孟代尔等己开始合力提升此产能，估计到2030年左右，以沙化草原的约46 %的面积种植巨量的巨银草，可使中国开始不再依赖石油和煤炭的化石能源，而转用由巨大的“巨银草油田群”供应的可再生的清洁能源，其余的面积的产量可供外销或作他用，使中国能长期成为世界能源强国，与他国合力稳定能源供应和价格，并引领世界迈向可再生的清洁能源新时代。

China has vast areas of desertified grass lands, totaled around 40 % of the national land area. These lands are not suitable and have not been used for food production. But after extensive ecological re-construction, they can produce bountiful harvest each year of giant silver grass (botanically known as "miscanthus x giganteus"  and is named after its partially silver color). This is a perennial grass with a lifespan around 15 years and is native to northern sections of China and Japan. It can survive in poor and decayed environment and can grow up to a giant 3.5 m tall, strong and dense wild grass and can live on saline water intake. After harvested with special machinery developed in Europe, it can be gasified and catalyzed and may yield around 17.2 tonne of bio-butanol per hectacre. Bio-butanol can be used as a renewable and clean fuel directly replacing the non-renewable gasoline or petroleum. With joint efforts announced by the biology and microbiology expert teams of Monsanto, Mondel and others, this productivity is expected to be improved further. Hence it is estimated that around year 2030 and by extensively planting giant-silver-grass over 46 % of the vast desertified grass lands, China may become independent of petroleum and coal and turn to the vast "giant-silver-grass oil-fields"  forrenewable and clean energy. Harvest from the remaining areas can be used for exports or for other uses. Then China can become a world-leading supplier of clean and renewable energy. It can work with other countries to stablize energy supply and energy price over long durations. It can lead the world to a new age of clean and renewable energy with stable energy supply.
