Renewable Energy

These days everybody is concerned about the growing amount of their energy bills, now the solar option is available to reduce your dependence on utility companies. That would mean a reduced energy bill and savings obviously with just an effort required in making your solar cells and panel. It is necessary that you take and follow guidance in the cells and panel making process.

Some every day tools that we use and perhaps an access to a work shop is all you require to be able to build yourself a solar cell at home. One of the numerous advantages of a solar cell is that it is renewable and the energy it would generate would be much cheaper as compared to the utility company rates.

The Solar Cell working

The working of a solar cell working may be understood keeping in view the photosynthesis process of plant with the help of chlorophyll pigment present in them. The solar cells do the same, they obtain energy from the sun and convert it into current with the help of silicon in them.

Advancement of Solar Technology

Solar cell technology has grown more and more efficient with time, now it is possible to power your complete house with the solar energy and almost eliminate your dependence on the power companies and their bills.

The greenhouse effect is a natural process by which the earth keeps itself warm enough for the living organisms to survive. However, due to the human intervention, the level of these greenhouse gases has increased to such an extent that the greenhouse effect is become hazardous for human life.

Greenhouse gases are heat trapping gases formed on earth through natural processes and human activities, which then enter the atmosphere. Here are some of the major gases responsible for the greenhouse effect.

1. Carbon dioxide (CO2)

Carbon dioxide is being emitted in the air constantly as every time you breathe, a tiny amount of CO2 enters the atmosphere. However, this is an extremely small amount as compared to the CO2 produced when wood and fossil fuels such as oil, natural gas, and coal are burnt. Many other industries also produce CO2 as a by product. Although plants get rid of the CO2 present in the air during photosynthesis. With the increase in the fossil fuel combustion and deforestation, atmospheric CO2 has increased greatly. Carbon dioxide is accountable for most of the global warming, and with the ongoing rate, atmospheric CO2 level can almost double as soon as in 2050.

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.

Biomass energy is having so many benefits for the environment such as reducing air and water pollution, increasing soil fertility and reducing erosion, and improvement of the wildlife habitat.

Carbon Cycle

Carbon cycle is a way of nature for moving carbon around the Earth to support life on it. Carbon dioxide (CO2) gas is the most common carbon item in which one carbon atom is bound with two oxygen atoms.

Photosynthesis in the plant’s leaves breaks the carbon dioxide in to two, which keeps the carbon for making carbohydrates, and oxygen is exhaled in the air. So when plant dies or it is harvested for burning then it gives back the carbon to air, and that carbon is absorbed again by plants.

Solar energy is essential for our survival.It’s benefits are so many in numbers, such as it helps us in warming us and also benefit for other living things in the world.But its use in the commercial power production also.Solar power is also important for the plant life. because it is necessary for photosynthesis, (photo- mean light,synthesis- mean putting together) the process in which energy of sunlight is used by green plants to build up complex substances from carbon-dioxide and water.

Through this process food is produced for other living things it produces an oxygen for our survival for breathing and remove carbon-dioxide from the atmosphere.And we get clean and clear environment.Beside of all these advantages it also maintain balanced a world temperature entirely.There are many kinds of solar energy,such as hybrid solar lighting,which is used inside for our facilitation.

Solar energy is extremely important for us to survive. Besides helping us to stay warm, and enabling other organisms to survive, it is used in the commercial power production as well.

Solar energy is also essential for plant life as it is necessary for photosynthesis, the process through which plants generate energy and process nutrients for their growth by converting solar light for their own use by utilizing chloroplasts within their leaves and bodies.

Through this process, food is produced for other herbivores together with oxygen for us to breath and removal of carbon dioxide from the atmosphere, allowing creatures such as ourselves to survive while maintaining a balanced world temperature.

According to recent reports, scientists are working together progressively to develop an “artificial leaf” that imitates the working of a real leaf, i.e. the chemical magic done through photosynthesis.

However, instead of food for the plant, the new leaf converts sunlight and water into a liquid fuel such as methanol for cars and trucks.

The report came from top authorities on solar energy, who met at the 1st Annual Chemical Sciences and Society Symposium. The authorities stressed on initiating international cooperation and novel thinking on the global energy challenge.

Since the usage of solar energy is dependent on regular provision of energy, storage systems are the important part that needs to be look upon to move towards the era of personalized solar energy.

The emphasis of this article is more on production of energy in people homes rather than big central generating stations.

How Solar Energy Can Be Saved?

According to the new paper by Massachusetts Institute of Technology (MIT) Professor Daniel Nocera explains the expansion and improvement of the less costly storage system of inexpensive storage method for achieving tailored solar energy. It uses a catalyst that separates water molecules into oxygen and hydrogen.

In a few years time homeowners would be able to power their homes in daylight with solar photovoltaic cells, while using excess solar energy to produce hydrogen and oxygen from water to power a household fuel cell. If the new process developed at the Massachusetts Institute of Technology finds acceptance in the marketplace, electricity-by-wire from a central source could be a thing of the past.

Solar power has always been a limited, far-off solution. Now we can seriously think about solar power as unlimited. Until now, solar power has been a daytime-only energy source, because storing extra solar energy for later use is expensive and inefficient. But Nocera and his team of researchers have hit upon an elegant solution.
