Earth Day is celebrated on two different dates in a year. The celebrations are carried out with great enthusiasm worldwide on both dates. The Earth Day was first time celebrated on April 22, 1970. Senator Gaylord started the celebration of Earth Day and he raised the awareness among people to take the responsibility of earth and life on earth. On 20^th March, 1978, McConnell started celebrations of Earth Day nearly with the time of vernal equinox. Earth Day is celebrated with great keenness and unanimous passion simultaneously in all parts of the world on the same day. People having different backgrounds, beliefs, nationals, and religions add their part in the universal celebrations of Earth day.

Every year, according to a careful estimate, there are approximately more than one and half billion individuals who take part in various Earth Day campaigns. When this movement of saving life on earth started in 1970 on April 22, nearly 20 million Americans took part in this movement to achieve the goal of a hygienic and sustainable environment.

Wind and sun are the most familiar forms of renewable energy. While biomass (plant material and animal waste) provides 15 times more energy in United States than wind and solar power combined and still have potential to supply more.

There is a vast range of biomass energy resources, that includes tree, grass, crops, forestry, agricultural, and urban wastes. Biomass is the oldest source of renewable energy used by humans when they known how to burn fire.

Renewable energy that is the hottest of the focal point in current times cannot be used up and it does not generate pollution. Sustainability means that we make sure we meet our energy needs and ensure the health of the planet for future generations. Eventually, we will run out of nonrenewable energy supplies and the pollution caused by using these energy sources is already becoming a serious problem. The sooner we switch to using renewable energy, the cleaner the air we breathe and water we drink will be. Among these renewable energy resources the foldable wind generator is also one of the innovations but there is still a question mark on its development.

Eolic design has been introduced in foldable wind generator class but it is uncertain as to whether it’s capable or not. The Eolic looks great and is an incredible idea, but can it actually create enough energy to power anything and is it durable enough to actually hold its ground in a wind strong enough to create electricity? Still it’s an ambitious idea and we have to sit back and see its viability.

There are numerous types of plants and so many ways from which energy can be produced in the world. Typically there are two approaches for using biomass energy, one is growing plants for energy use and second is using plant’s residues for other things. There is no best approach for using biomass energy because of climate differences from region to region, soils, geography, population and other such things.

Energy Crops

Energy crops or power crops can be grown in farms on massive level just like food crops. Best energy crops are the trees and grasses while other less agriculturally sustainable crops like corn tend can be used also for energy purposes.

As the demand for the renewable energy resources is increasing, so is the number of consultants offering their services and expertise. If you intend to install some renewable energy plant at your house or office, you would surely need the help of some consultant that would guide you about the right way of doing so, so that you can take maximum advantage of your plan.

How a consultant can be helpful?

A good renewable energy consultant in this regard would be better capable of guiding you about the aspects that you need to consider while installing the renewable energy plant, he can offer you his expertise in the amount of finances that you would be required to have, and many other options that you have in this regard.

Tidal energy is used to generate electricity through the use of tidal energy generators. By placing large underwater turbines in areas with high tidal movements, they are used to capture the kinetic motion of the ebbing and surging of ocean tides in order to generate electricity.

Tidal power is a great source of renewable energy, offering great potential for future power and electricity generation due to the massive size of the oceans.

Advantages of Tidal Energy

• Apart from the initial installation cost, tidal power is free.
• Tidal energy produces no greenhouse gases or any other kind of pollution.
• It requires no fuel.
• Electricity is produced reliably.

Tidal energy is a great source of clean renewable energy, but most of us don’t know about how it works? Every day, the tide moves a huge amount of water twice, and harnessing it could provide a great deal of energy, which can make up around 20% of Britain’s needs.

The energy generated through this process is reliable and plentiful, but converting it into useful electrical power is not easy. Some time back, “tidal power” meant “tidal barrage”,but nowadays there are other options as well.

The working of a tidal barrage is similar to a hydro-electric scheme, except that the dam is much bigger. A huge dam called a “barrage”, is built across a river estuary. When the tide goes in and out, the water flows through tunnels in the dam.

We are all aware of the harmful effects of global warming, but there can be many ways to prevent global warming. Although we can’t prevent global warming completely, we can sure help to reduce the intensity of the future effects of global warming.

Here are some steps that we can take in our daily lives to prevent global warming effects.

• Use transportation only for travelling to far off areas. Try walking for short journeys or using a bicycle more frequently.
• Share transportation and do car-pooling whenever possible.
• Drive in the correct gear to reduce fuel usage. Keep all windows shut on warm days if you have air conditioning to maximize fuel efficiency.
• Consider purchasing a hybrid or electric vehicle when looking for a new car.

According to the largest utility company in California, it plans to purchase more solar power from businesses and individuals.

A few weeks back, Governor Schwarzenegger said that he wanted California to get at least a third of its power supply from sustainable and renewable sources such as wind, solar, and hydroelectric power.

Keeping this in view, Pacific Gas & Electric (PG&E), which is the biggest utility company in California, suggested acquiring more solar power, in order to increase the practice of residential rooftop solar panels.

First Solar Inc., which is a U.S.-based renewable energy company, is going to build the world’s largest solar power plant in China as the country plans to increase electricity generation without pollution.

Dulce Qu, who is a Beijing-based spokeswoman for company, said by telephone today that the plant would be about thirty times larger as compared to the existing solar power stations that are operating in Europe. Arizona-based First Solar said yesterday that by 2019 the 2,000-megawatt complex will be built in Ordos City, Inner Mongolia, China, Tempe. One mega watt would be enough to power 800 U.S. homes.

China, which is the world’s biggest polluter, burns coal in order to produce 80% of the electricity consumed by them and wants at least 15% of the nation’s energy to come from renewable sources by 2020. The U.S. and China are making efforts for reducing emissions of gases blamed for global warming, and it has been reported by the New York Times yesterday that Bechtel Corp. plans to build a solar station in California.

It has been observed in the Government’s Renewable Energy Strategy paper produced last month, that the Government’s plans to increase the proportion of Britain’s energy generated by "green" sources is set to cost between 11 and 17 times what the change brings in economic benefits. But the figures have been buried deep down in the report.

The document states that while the expected cost will total around £4bn a year over the next 20 years, amounting to £57bn to £70bn, the eventual benefit in terms of the reduced carbon dioxide emissions will be only £4bn to £5bn over that entire period.
