Currently energy in the form of electricity is stored by the following methods. Why electricity? The main reason is its versatility to convert to other forms of energy, like light, heat, movement makes it the best candidate. Another reason is that we can effectively store electricity.
- Nuclear
- Wind turbine
- Hydroelectric generation
- Bio Gas – using manure that decomposes and produce methane which can be harvested and burned
- Bio Alternatives – Bio Diesel which can be manufactured from plants such as fast growing algae
- Solar electricity harvesting
Green Computing
Just started to help in running Green Computing at University of Kent. So what is green computing? according to Wiki:
Green computing, or green information technology (IT), refers to environmentally sustainable computing. It is the study and practice of using computing resources efficiently by designing, manufacturing, using, and disposing of computers, servers, and associated subsystems (such as monitors, printers, storage devices, and networking and communication systems) with minimal or no impact on the environment. Green computing strives for economic practicality and improved system performance while satisfying social and ethical responsibilities. Green computing includes the dimensions of environmental sustainability, energy efficiency economics, and total cost of ownership (which includes the cost of disposals and recycling).”
Green computing can be made more sustainable in several ways including:
- Placing the computer in hibernation mode
- Switching the computer screen off instead of using screensavers
- Turning the computer off when it is not in use
