Renewable energy

Renewable energy is energy that can be replenished easily. For years we have been using sources like wood, sun, water, etc. for means for producing energy. Energy that can be produced by natural objects like wood, sun, wind, etc. is considered to be renewable.[1]

Water purification

Water purification: The whole idea/concept of having dirt/germ/pollution free water flowing throughout the environment. Many other phenomena lead from this concept of purification of water. Water pollution is the main enemy of this concept, and various campaigns and activists have been organized around the world to help purify water.[2]

Air purification

Air purification: Basic and common green plants can be grown indoors to keep air fresh because all plants remove CO2 and convert it intooxygen. The best examples are: Dypsis lutescens, Sansevieria trifasciata, and Epipremnum aureum.[3]

Sewage treatment

Sewage treatment is conceptually similar to water purification. Sewage treatments are very important as they purify water per levels of its pollution. The more polluted water is not used for anything, and the least polluted water is supplied to places where water is used affluently. It may lead to various other concepts of environmental protection, sustainability etc.[4]

Environmental remediation

Environmental remediation is the removal of pollutants or contaminants for the general protection of the environment. This is accomplished by various chemical, biological, and bulk movements. (encyclopedia of medical concepts)[5]

Solid waste management

Solid waste management is the purification, consumption, reuse, disposal and treatment of solid waste that is undertaken by the government or the ruling bodies of a city/town.[6]

eGain forecasting

Egain forecasting is a method using forecasting technology to predict the future weather's impact on a building.[7] By adjusting the heat based on the weather forecast, the system eliminates redundant use of heat, thus reducing the energy consumption and the emission ofgreenhouse gases.[8]

Energy conservation

Energy conservation is the utilization of devices that require smaller amounts of energy in order to reduce the consumption of electricity. Reducing the use of electricity causes less fossil fuels to be burned to provide that electricity.

History of Tamil cuisine(Regional Cuisine & Meals - Restaurant)

Regional Cuisine   [ edit ] Over a period of time, each geographical area where Tamils have lived has developed its own distinct variant of the common dishes in addition to dishes native to itself. The four divisions of ancient Tamilakam  are the primary means of dividing Tamil cuisine. The  Chettinad  region comprising  Karaikudi  and adjoining areas is known for both traditional vegetarian dishes like  idiyappam ,  uthappam ,  paal paniyaram  and non-vegetarian dishes made primarily using  chicken .  Chettinad cuisine  has gained popularity in non-Tamil speaking areas as well. [ citation needed ] Madurai ,  Tirunelveli  and the other southern  districts of Tamil Nadu  are known for non-vegetarian food made of  mutton , chicken and  fish .  Parota  made with  maida  or all-purpose flour, and loosely similar to the north Indian wheat flour-based  Paratha , is served at food outlets in Tamil Nadu, especially in districts like  Madurai ,  Virudhunagar ,  Tuticorin ,  Tirunelveli
