Global warming and Green House Effect are major environmental problems that are responsible for ecological imbalance. Carbon emissions from vehicles and factories have resulted in increasing environmental pollution and there is a drastic climate change throughout the earth. On the other hand, the green movement has initiated owing to environmental awareness around the world. Green hosting has emerged with the objective of providing an environment-friendly solution for hosting services. The power consumption rate of the hosting industry has been increasing in proportion to the incredible reach of the Internet. Many hosting companies have accepted the emerging concept owing to the demand on power sources.
 
Green hosting facilitates the use of power generated from renewable resources like wind power, solar power and hydro power to operate the servers and the datacenter infrastructure. Several companies have their own wind turbines or solar panels to power their servers. Installation of such generators is a one-time expenditure that renders self-sufficiency and brings more profits for the web host.  

Studies have shown that on an average, a website generates about twenty milligrams of carbon dioxide per second, and that fifty million tons of carbon dioxide is likely to be emitted by 2020 because of the Internet’s power consumption. Apart from web hosts, consumers too can help the environment by attempting to develop greener websites. Another means to contribute is by choosing server computers that are energy-efficient and devoid of materials that sensitize the environment. The influence of a computer on the environment is rated by rating systems such as EPEAT, i.e., Electronic Product Environment Assessment Tool, and Energy Star. Energy utilization of websites can be offset with the help of carbon offsets that can be purchased. Many countries promote environment-friendly hosting, and companies that have gone green are eligible for tax benefits.
 
The green movement helps bring a favorable balance between ecology and technology, as the balance is mandatory for sustaining survival on the earth. Hosting companies have been able to save huge amounts of money due to green energy, without which they would have spent it on non-renewable resources. Green energy has not only helped preserve valuable natural resources to regenerate for the coming generations but also helped lessen the threat to the ozone layer and maintain the important ecological system. Environment-conscious consumers willingly opt for hosting providers that have gone green. The amount saved on energy costs due to green web hosting is used by hosting providers to provide interesting deals and economical hosting plans to their clients.
