Solar Power System in the Home

With the so many alternatives for fossil fuel developing in recent years, solar energy has become very popular especially for use in homes. It is important to know how solar power systems work and possibly how to set them up.2KW-On-Grid-Home-Solar-Power-System

There are so many companies that now produce solar panels, and even at reduced prices. Having these solar energy products in your home will really save a lot of money for you, because the source of energy keeps renewing itself as it is coming from the sun.

It is so convenient because once you set up the solar energy system; it continues to generate electricity without the monthly costs associated with the regular source of power.

This is the major reason most people today are looking at ways of using solar energy in their homes; and in the near future, it is going to increase significantly. So it makes sense to start using it as soon as possible, we hope that very soon some homes could become completely independent of the power companies.

Whether these power companies accept this truth or not, is yet to be clear. But the earlier they realize that solar energy will soon become the main source of electricity in homes, the better for them and their business viability.

You can easily find companies selling solar products online. Ask questions and find out the best products that suits your home the most. You don’t have to try replacing the normal source of power all at once; it has to be a gradual process.

Make sure you make appropriate considerations before you install the solar system; however, we all know it is a much better alternative to fossil power in the long run.

Nuclear Energy – How Feasible?

The incidents of the Fukushima disaster are still fresh in the memory, especially to those in Japan and other eastern countries. There have also been other nuclear disasters recorded in history. This explains why so many people are against the use of nuclear energy.Oil Refinery

Looking at countries that actually have the resources to implement nuclear power plants, it seems as though they really just have no option but to use it. Japan for example, are already looking at restarting their use nuclear power plant considering the economy and the need to keep business and commerce going in the country.

Also, China’s pollution from their coal plants has become very severe in the atmosphere. And now they just need to figure out an alternative way of generating electricity, so people can at least have fresh air to breathe.

The challenges posed by producing energy through nuclear plants have been identified: the cost, its safety, managing its waste and the risk of proliferation.

Taking a closer look at those challenges, it is possible to develop technologies that can eliminate the risks associated with nuclear energy. They will be developed as small reactors that can take care of cost, safety and managing of the nuclear wastes.

The small reactors will also use up to 95% of the nuclear fuel, preventing the unused fuel from accumulating for a long time.

Really, the time has come for the world to begin looking at the possibility of harnessing nuclear energy as a source of power.

Steps To Repair a Damaged Lawn

Once in a while we observe that the lawns in our homes are damaged or looked patched. This can be caused by several factors such as harmful insects, weeds or lack of care. We repair the damaged lawn to restore its fresh and green appearance. The earlier it is done the better.

damaged lawn

The steps here will give a head start in repairing your damaged lawn.

Water continuously

Applying enough water can help bring the grasses back to life. To measure how much water is enough, keep a food can during sprinkling. Once it accumulates half inch of water, you can stop

Replace the patches

With a small hand shovel, remove the soil surface of dead spots or patches and water it. You can also spread seeds and observe the spot until grasses sprout up.

Apply the fertilizers

Visit your local store and use any proven fertilizer application product that help give your lawn the appropriate nutrients it needs; as well as strengthen grass roots in the soil.

Clear any dead grasses

Dead grasses are just dead. Take them out with a rake and replace with seeds. You can spread a few of the dead grasses and water appropriately.

Uproot any weeds

Though this step is last here, it can even be done first, considering how important it is to the growth of the grasses in your lawn. Watch and make sure that weeds are uprooted. Also don’t allow plants from your plant bed to begin appearing on your lawns.

Generally, it is important to take care of your lawns and prevent any of the above from the outset. This will give the grasses longer life, and eliminate the stress of repairing a damaged lawn.

How Eco-friendly is Wind Energy?


There has been so much rave about eco-friendly ways of generating energy in our world today. One of such is by using wind turbines that are powered by high currents of wind.

On close observation of how tapping energy from wind occurs, one begins to wonder if it doesn’t go contrary to the whole essence of green energy production.

First, the fact that wind is not available at every point in time keeps the turbines idle at these times, making them unreliable. Sometimes too, when the wind comes, it could come with such velocity that the turbines will be turned off, so they don’t catch fire and disintegrate.

Also, as long as we are concerned about our environment, we have to take note of the birds and bats the rotating blades of the turbines kill at every point in time. Not to mention the uncomfortable sounds it produces when it is rotating. The sounds have damaging effects on mammals especially.

As for emissions, the concrete base and towers of steel produces a lot of carbon dioxide emissions into the environment. This doesn’t mean greenness in any sense.

Furthermore, costs of maintaining a wind turbine is high. Each of its motor lasts just for 10 to 15 years, including the costs involved in installing its transmission lines.

So there needs to be a reassessment of how green the energy produced by wind technology really is. There has to be a way of minimizing its negative impacts in the environment, or reducing its general maintenance costs.

Sustainability of the World’s Ocean Fishes

Research studies have shown that the population of fishes presents in our ocean today is just 10 percent the number they were before the boom in industrialization. This means that they are currently under pressure, and scientists have warned that by 2050, the fisheries could collapse significantly.

Although large populations of fishes have demonstrated the ability to recover, especially when managed properly; there is need to enforce regulations that protect fishes from excessive fishing and ensure their sustainability.

EU fishing quota : Fishermen in Spain

To contribute to the sustainability of fishes, it has to start with providing more information to the consumers. By identifying fishes properly via tracking, from the ocean to the plate, the consumers will be able to know where and when fish was caught.

Also, by tracking, fishes can be labeled properly so that the consumers have the choice over the kind of fish they want to eat. Sustainability can really be maintained when we know where fishes come from and exactly how it was caught.

Take for instance, a fish that was caught about 30 days ago and one that was caught just yesterday are both called ‘fresh fishes’ by a fish seller.

When consumers understand the importance of eating only the really ‘fresh fishes’, and also understand its distribution, then the fishing process will gradually become more sustainable.

To achieve this, a tracking technology could help answer some sustainability questions such as: was the fish caught using a fish aggregating device, and how legal was the catch?

With that, the sustainability of fishes in our ocean can begin to be taken more seriously.

Eco-friendly Way of Disposing Old Computers

The use of computers in homes have increased tremendously, and as tech companies manufacture better ones; it becomes obvious that there has to be a way of disposing of the older ones that are either outdated or no longer in use.

A lot of times, repairing old computers doesn’t make sense, because the cost could far outweigh the entire value of the computer. So it becomes even cheaper and better to buy a new one.

In disposing of computers, you have to realize that the computer components carry poisonous substances like mercury, cadmium and lead. The lead is majorly found in the monitor of those old cathode-ray computer screens.

Recycling plant tellies and monitors Norway.

Flame retardants like polybrominated diphenyl ethers, antimony trioxide, polychlorinated biphenyls and polybrominated biphenyls, are also present. This makes surplus computers in a home to be considered as hazardous waste by the Canadian Environmental Protection Act.

So to avoid the risk of contaminating our environment with heavy chemicals, recycling the computers will ensure that the glasses, metals and plastics are not wasted.

In fact, these resources from the computers can be used in the production of newer computers, while at the same time saving our ecosystem from the risks associated with environmental pollution.

You definitely wouldn’t have realized that by recycling a million computers, the amount of energy equivalent required in about 4,000 homes would have been saved.

By recycling, you also protect even your deleted personal data from your hard disk too. But ultimately, it makes so much sense to hand over your used and outdated computers to recyclers, in order to save our environment.

Eco-friendly and Healthy living

When we say a something is eco-friendly, it means that it does not cause damage to the environment. Put in another way, eco-friendly means earth friendly, or environment friendly.

We can be eco-friendly, both in our activities and habits at home, work and especially in the way we make use of the resources we have in our environment.

Eco-friendly habits in our homes

There are so several things we can do to preserve resources in our homes, offices and businesses.

In our homes, we can turn off the lights in empty rooms. Likewise, the use of automatic thermostats should only be used when people are around. Regulating electrical gadgets this way goes a long way to preventing the release and wasting of energy from them.

Eco-friendly Products

mini-hydro-greenhouse

Basically, when we see eco-friendly on products, it suggests that the product is non-toxic. It also means that the ingredients that were used in the production process of the product were prepared in such a way that conserves resources and preserves the ecosystem.

If organic ingredients were used, it means that they were grown naturally without the use of pesticides that could be toxic at some levels. Recycled materials, contain glass, plastic or wood extracted from wasted materials; and converted into another product.

There are also products that are biodegradable, which suggests that after use they naturally break down in the soil.

So with this you can improve healthy living and manage resources in the ecosystem.

Earth’s Future Climate – Hopeful of Bleak?

Over the years, we have seen our beautiful world suffer from serious emissions that have threatened the natural beauty of our environment. The emission from the earth has contributed to the warming of the earth’s climate.

Scientists have already projected that if the emissions persist, then we could see the earth’s temperature increasing up to an additional 4 degrees later in this century.

So are we doing enough to stem the tide? The truth is that if tough decisions are not taken quickly and drastic, then we’ll soon be living in crises mode.

Feasible ways of halting climate change:

The United Nations Environment Programme (UNEP) discovered that by 2050 the emissions from the earth need to be about 50% below its current levels; in their Emissions Gap Report of 2012. So, how can this gap be closed up?

There has to be total compliance with every agreement regarding reduction of green house emissions. The UNEP and other bodies concerned have to implement policies that not only go a long way to achieving emissions objective; but that are also interesting for the concerned nations to pursue.

Take for instance, implementing a better performance standard for public vehicles and buses, will obviously bring down carbon emissions, benefit the environment and enhance quality of air in cities.

Also, there has to be concerted effort in helping under-developed and developing countries adopt a low carbon economy. This can be achieved through quality policy making, and creative information technology systems.
