You Can Make Your Own Solar Power

The sun’s energy, commonly known as Solar Energy, is the most abundant form of energy available on earth. The sun is capable of giving us more than heat and light. The sun has been one of the biggest factors dictating every living being’s stay on the earth. If we go the right path, we can harness more of the solar energy, easily generating cheap power for daily use.

What are the advantages of solar power?

The solar energy solution has always been the most popular amongst the alternate energy solutions.

Personally, I think this is because we “understand it” better than all the others. We all know that lying supine in the sun will turn us to the colour and texture of perfectly cooked lobsters and we also know that the cooking process requires ‘energy’.

It’s not too much of a mental leap to understand that the sun produces energy – for most people, anyway

Now, on to the benefits of using ‘Green Energy’.

Green energy solution: When you look at the solar energy solution, you will realize that it uses absolutely no fuel other than the sun’s light. Moreover, it does not release into the atmosphere anything harmful. Pretty good idea, don’t you think?

Cheapest power solution: First, the energy comes free. Then, the installation cost is a one-time cost. Finally, the investment is recovered within a few years of installation, making the power generated by solar energy absolutely free.

At the rate power prices are rising, at the moment, it will take no time at all to pay for itself!

Convenience of storage: You cannot store conventional power but you can store solar power for future use. The sun’s energy comes to the rescue even in the times of darkness! Storing it also ensures a 24×7 supply of power, thus saving you from any power outage. (Laugh At Your Neighbours floundering around in the dark!)

• Low on maintenance: The solar energy systems are easy to maintain. They do not involve high costs or too much effort, letting you reap the benefits of the solution comfortably. “Not Much”, my favourite kind of effort.

How can solar power be used?
Solar power can be used in our everyday lives by adopting the following solar power systems:

Solar cooking system: Solar cooking is about cooking without lighting a fire or using electricity! Before you wonder, let me tell you that solar cooking is not about bland food. You can cook in more ways than one – boil, roast, or bake, cook the way you want! The only demand that solar cooking makes of you is being patient; it is a matter of more than a few minutes. However, it is not asking for too much given that you will get tasteful and healthy food without worrying about paying your gas or electricity bill.

Solar lighting system: You can now light up the entire house, use every electrical appliance without thinking about cutting down bills. There Are No Bills! The solar lighting system lights up your house even on the darkest nights, thanks to the power storage feature it has.

Solar heating system: You can keep your house cozy and warm using the solar heating system without worrying about costs.

There you are, then. An altogether first class idea, I think.

How Can Energy Revolution Cut Down Global Warming?

Friday, July 31st, 2009

Energy is imperative that touches every corner of the economy and can alter people’s lives in numerous ways. We need energy to light our homes, to help us travel and to power our businesses. The resources of fossil fuels – coal, oil and gas have benefited our economy.

Currently, energy system is facing new challenges. Earlier, energy was supposed to be a domestic issue but today the entire world is concerned over this. Burning of fossil fuel is causing climate change for which we are going to be penalized by the nature. Before it gets late, we need to address the threat of climate change. Globally, the gas and oil reserve is dwindling and if we let the climate change happen, it will devastate the economies and ecosystem across the world. Climate change will lead to temperature change, drought, and flood.

Recent climate simulation states that Carbon Dioxide emission will need to peak within the next decade and decline by at least 50% to 80% by 2050. This challenge will be greatly complicated by the fact that China, India, and other developing countries are now rapidly developing modern energy systems. Scientists studying climate change say carbon capture from power plants is essential, if the country is to take up the challenge against global warming.

The world is now in the early stages of an ‘energy revolution’ and we want to avoid catastrophic scenario. For that we will need an updated energy infrastructure that can integrate ‘renewable’ energy sources – such as bio energy, wave or tidal, wind, and solar power – that do not add to global warming. Renewable and efficiency technologies will allow developing countries to increase their reliance on indigenous resources and reduce their dependence on expensive and unstable imported fuels.

Resource estimates indicate that renewable energy is more abundant than all of the fossil fuels combined and well before mid-century it will be possible to run most national electricity systems with minimal fossil fuels and only 10% of the carbon emissions they produce today. The development of smart electricity grids, the integration of plug-in electric vehicles, and the addition of limited storage capacity will allow power to be provided without the baseload plants that are the foundation of today’s electricity systems.

Another challenge is the variation in the power supplied by renewable energy sources, wind varies with the weather while tides may be predictable but will only coincide with peak demand for power some of the time. Today, consumers are used to getting power whenever they want and will never be pleased if they can not watch television until the tidal condition becomes favorable. We will also have to think if we can look at things from consumer point of view. Maybe any future network should have a say in how many power-hungry devices we run at once, perhaps switching off your fridge for the short period when the kettle is on?

Every country is contributing heat trapping gases to the atmosphere which is getting collected as a thick blanket, trapping sun’s heat and eventually leading to global warming and climate change. This will affect one and all and will be almost impossible to turn around the consequences. The biggest challenge here lies with the developing nations as talks on emission cuts are underway and developing nations are insisting that reduction should be imposed only on developed countries because they are solely responsible for today’s concern. The fact of the matter is that the world needs energy diversification and efficiency program and every country should take part in this so that we all have a common goal and we can work towards it.

How Do Plants Get Nutrients in the Soil in a Conventional Farming System?

Thursday, July 30th, 2009

Plants need an adequate supply of nutrients — particularly nitrogen, phosphorus, and potassium — to grow well. Ideally, these nutrients should be available in the proper quantity and at the time the plant can use them. This ideal timing, if complied with, will help farmers avoid supplying an excess of nutrients that plants cannot use anyway and may become contaminants in the environment instead.

Nitrogen, phosphorus and potassium are the nutrient elements most needed in large amounts by plants; however, they are not available in adequate amounts in the soil. Nitrogen is important for plants because it is a component of proteins and chlorophyll, the active pigment in photosynthesis; it is a constituent of nucleic acids and coenzymes that catalyse cell reactions. Phosphorus is also found in proteins, coenzymes, and nucleic acids; it is critical in metabolism and chemical energy generation and utilisation in the cells. Whilst its role is not clearly defined as a component of the various chemical compounds that make up the plant, potassium is important in the physiological mechanisms that regulate plant processes, particularly the all important processes of photosynthesis and carbohydrate translocation.

In conventional farming systems, nitrogen, phosphorus and potassium are supplied to the soil by application of inorganic fertilisers at levels recommended by soil testing technicians. The caveat is that variable conditions in the soil and the climate affect the rate of uptake or loss of nutrients in ways not yet fully understood. The ability to forecast factors that influence the storage, cycling, availability and uptake of nutrients is still relatively inadequate. This makes it difficult to predict the proper, environmentally safe levels of nutrients. Consequently, the application recommendations that farmers receive may just as easily lead either to insufficient or excessive fertilisation.

Working out the appropriate dosage amounts to apply may be tricky. Phosphorus fertiliser undergoes rapid conversion into less soluble compounds in acidic or alkaline soil, which then severely limits their availability for plant nutrition. Even if they are in available forms, the phosphorus may be tightly bound to organic soil compounds and clay, and remain locked in soil, inaccessible by plants. On the other hand, potassium and nitrogen (in its ammonium and nitrate forms) have greater solubility than phosphorus. Nitrate ions will leach readily into the soil, thus nutrient applications are susceptible to significant losses. Potassium and ammonium nitrogen are positively charged and are held on by negatively charged soil in the cation exchange, thus leaching will not occur in appreciable amounts except in sandy soils. Whilst there is understanding of the basic process, agriculture scientists need more information about nutrient cycling and nitrogen behaviour under various environmental conditions.

As a result of this difficulty, it is not surprising — and many studies have found — that recommended fertiliser doses worked out by some commercial soil testing laboratories consistently required far more fertiliser than was needed. Not only that, some farmers tend to apply greater amounts of nitrogen than recommended. However, with susceptibility to leaching and/or rapid conversion into insoluble forms, there is still no guarantee that the fertilisers will still be available to plants at the time plants have need for them.

Save Money and the Environment by Asking Questions

Thursday, July 30th, 2009

From tariffs to climate change, renewable energy and prices, there are many questions you might have when it comes to your electricity and/or gas accounts. Instead of keeping quiet why not ask the questions you would like answers to and take part in shaping the future of your energy needs and use.

Many people do not realise there are various different energy tariffs to choose from. The value of your energy bill will depend on the tariff you select, the unit costs for electricity or gas consumed and the method by which you wish to pay.

If you are on a credit meter tariff, where you pay for your energy after you use it, then you will have several options to choose from depending on which provider you use. Some providers operate a standard rate electricity tariff which is suitable for customers who use most of their electricity during the day. This type of tariff is also useful if you do not use electricity to heat your house and/or hot water.

If you use most of your electricity at night time then it makes sense to opt for a two rate meter where there is a higher unit rate for electricity used during the day, but a much cheaper rate for units of electricity used during at night. Depending on energy provider this is also referred to as Economy 7 Electricity. Check the terms and conditions for details as you may need to use your electricity within a certain time period at night.

Prepayment meter tariffs, where you top your meter up with credit in advance, are a convenient way for many people to effectively manage the amount of energy they use. This is a ‘pay as you go’ approach to settling your gas and electricity bills and means you do not get an unexpected bill which you might struggle to pay.

If you have questions about tariffs designed specifically for the elderly or low income families then get in touch with your provider as there may be an option to suit you. Some energy providers offer social tariffs which help the elderly, low income families, people with disabilities and the chronically sick and tend to be the least expensive option, regardless of payment method.

There are many more energy issues for you to ask questions about; you might need more information about gas safety checks or need some energy efficiency advice. But, whatever your query, just get in touch with your energy provider who should have the answers to any questions you might have.
