These are just the kind of plants used by the small-and medium-sized businesses that have been the engine of much of China's recent growth.
The fear, as propagated by the food processing industry and other critics, is that drug genes will hop to the chromosomes of plants used for food, contaminating the food supply with vaccines and drugs, in turn triggering costly recalls and potential legal liability.
They believe this indicates fire was used to encourage the growth of plants, such as hazelnuts, crab apples and raspberries, all which were eaten at the site.

The most that can take expected in the next five to ten years - the years that count for corporate investment and Federal pollution abatement policy is that fracgas will supplant 20% of coal otherwise used in power plants.
FORBES: Frack Gas Not Likely To Displace King Coal, Study Suggests
Both Mr Obama and Mr Harper made particular mention of carbon capture and sequestration, an unproven and expensive technology that could eventually be used on the coal plants that produce about 70% of American electricity, or on the upgraders and refineries in the tar sands.
If one could build power plants that used 80% of the energy instead, everyone would be rushing to do so, right?
With the share of natural gas used to fuel power plants expected to keep rising, gas producers are saying that between 29, 000 and 62, 000 miles of new pipeline is needed over the next 25 years.

With Enernoc, Brewster and Healy are pioneering a business idea that may save the U.S. from wasting a lot of capital on the power plants used to supply electricity during seasonal peaks.
New varieties of plants (whatever techniques are used to craft them) that normally harbor relatively high levels of toxins such as celery, squash and potatoes are analyzed carefully to make sure that levels of potentially harmful substances are still in the safe range.

Some maintained that many of the natural pesticides produced by plants were potentially more of a risk than the synthetic ones used in conventional agriculture.
The efficiency is of a comparable level to real plants used in the biomass energy source.
The researchers used a database of more than 16, 000 energy plants to determine which underused plants were likely to make up a power shortfall if specific nuclear plants were closed.

However, once built, these plants do not require fuel, although they will be tied to natural gas fuel costs as gas plants are generally used to buffer the intermittency of wind production, not included in this discussion.
The fig plants are used to provide shade in the atrium of the building, which MPs use to hold meetings with constituents and other visitors.
Secondly, when considering end-to-end efficiency, it is much less energy-intensive to heat water by direct use of natural gas on-site, rather than by using that natural gas to first make electricity that is used to heat water because of the large conversion losses at power plants.
U.S. firms, which provide 60% of the solar cells and panels used in India's power plants, are already unhappy with the local content requirements.
He thinks it might be used to cut the cost of hooking villages up to local electricity-generating plants, or to subsidise the prices charged.
