Global Issues: Ozone Depletion, Global Warming and Acid Rain

Introduction

Air pollution is exerting increasing impact on the environment. Humans have been altering the chemistry of the atmosphere on a global scale. These changes may:
Modify the global climate
Threaten the health of human beings
Create many environmental problems such as
Acid rain
Depletion of ozone layer
Global warming
Seriously upset the global ecosystem

What is ozone depletion?

What is HEP
HEP (Hydroelectric Power) is an environmentally friendly way to generate electricity.
How it works
A dam is built to trap water, usually in a valley where there is an existing lake.Water is allowed to flow through tunnels into the dam,to turn turbines and thus drive generators.Notice that the dam is much thicker at the bottom than at the top,because the pressure of the water increases with depth.
A picture of how it works
Where is the bes ....etc

I want all relevant information on availability of Technology in India for coal gasification & power generation through IGCC.
We have got assurance for supply of G-grade coal by SCCL,AP as much as we need & we want to carry out a Techno-economic Feasibility Study for 100 Mw IGCC power from syngas.

IGCC POWER PLANTS A new technology to answer global warming

INTRODUCTION
Developing cost-effective carbon capture technology is one of the most important environmental challenges facing the utility industry in the 21st century
.The process offers options to eliminate greenhouse gases, produce hydrogen and liquid fuels.
. The potential for carbon dioxide sequestration makes IGCC technology even more appealing and environmentally responsible. . A more complex, but even more economical option.
. In this techno ....etc

Abstract
Biogas technology, besides supplying
energy and manure, provides an excellent opportunity
for mitigation of greenhouse gas (GHG)
emission and reducing global warming through
substituting firewood for cooking, kerosene for
lighting and cooking and chemical fertilizers. A
study was undertaken to calculate (1) global
warming mitigation potential (GMP) and thereby
earning carbon credit of a family size biogas plant
in India, (2) GMP of the existing and target biogas
plants in the country and (3) atmos ....etc

What is the effect of global warming on plants?

Plants can easily be affected by even a gradual increase in temperatures. Small shifts in climate changes can harm a number of plant species. The plants of the mountain and Polar Regions are especially at harm from global warming. As ice in these areas melt, the plants are endangered because the ground becomes warmer than the usual temperature the plants are accustom to. While some plants are able to adapt to the temperature changes, many are not able to do so.
