Alternative Energy Sources – What is Alternative Energy?

Alternative Energy Sources - What is Alternative Energy?

Alternative energy sources, what is alternative energy you ask? The common definition for this tern is that it is an overall term used to refer to any source of usable energy intended to replace fuel sources, and in modern times, without the consequences of pollution or greenhouse gas emissions.

The term “alternative” in this case presupposes the current set of energy technologies against which “alternative energies” are compared. As such, the list of energy technologies excluded is an indicator of which problems the alternative technologies are intended to address. Controversies regarding dominant sources of energy and alternatives to them have a long history, ever since fire was discovered for a matter of fact. The nature of what is regarded as alternative energy sources have considerably changed over time, as with the technologies that we use to extract and utilize them. Currently, in this modern day and age, due to the wide variety of energy choices and differing goals and agenda’s of their advocates, defining some energy types as “alternative” has become highly controversial.

As such, big oil and coal don’t want to lose market share and are launching campaigns to dispel the harmful effects of their energy products .They want to keep that money rolling in, at whatever cost to the environment, and ultimately mankind. They prefer to keep things as they are, and are slow to adapt to the new wave of clean and renewable energy sources, however some progress is being made.

How To Install Solar Panels Yourself

How to install solar panels yourself

How to install solar panels yourself

How to install solar panels is a simple guide for the average do it yourselfer who has a little knowledge of electrical power. When you choose solar energy to power your home, you have chosen a simple way to save money by investing in free, renewable energy. Most of us these days don’t have the extra thousands of dollars laying around to hire a professional for installation, which by the way can cost in the tens of thousands of dollars, depending on your location and who you hire.

There are many of us that can’t afford those costs, including DIY enthusiasts such as yourselves have decided to learn how to install solar panels by themselves. If you can follow the directions to put together a desk, dresser or bookcase from a WalMart diy furniture kit, then you can more than likely learn how to install solar panels by yourself too! It is not that difficult!

In the following section, we describe the basics of this task, however before you start this diy project, you should remember this point. Always put your safety first when installing solar panels, especially if you are mounting them onto a roof. Check your local regulations in your area if there are any before buying solar panels for your home as some local laws may have specific rules and regulations about the maximum size of the panels and where they can be positioned.

Is Electricity Renewable or Non-Renewable? How to Find out if your Electricity is Renewable or Non-Renewable

Is electricity renewable? How to find out if your electricity is renewable or non-renewable. As it currently stands, our current grid and sources of energy come from a wide variety of sources and is not limited to a single power source. To begin with, first we must determine what the renewable and non-renewable energy sources are before we can fully understand and answer this question with a degree of honesty.

In short, electricity is largely produced by power stations burning fossil fuels like coal, oil, and natural gas. Nuclear fission can also be used to produce electricity from nuclear power plants. All these sources of energy are not renewable, which means that there is a finite, or limited amount of these fuels available in the world and when it is all used up, that’s it, there will be no more.

On the other hand, hydro, wind, tidal, geothermal, biomass, and solar power are all regarded as sustainable and renewable forms of energy because they aren’t finite and limited to available resources. We use the energy we obtain from these sources and it still keeps coming, it will not run out! Continue Reading Is Electricity Renewable or Non-Renewable?

Solar Renewable Energy – Is Solar Energy Renewable and Can it Meet our Energy Needs?

Solar Renewable Energy - Is Solar Energy Renewable and Can it Meet our Energy Needs?

Solar renewable energy, is solar energy renewable is a question many people ask us. It is also a question which is both easy and hard to answer, if that makes sense. It is clean energy, and it is sustainable, and at face value it is renewable, as the sun shines every day. However it is not renewable in the traditional sense that it can’t be replaced or regrown, like biofuels. However it is fairly consistent, and is present every day for up to 16 hours a day in some areas, and at the northern and southern poles, sometimes is visible 24 hours a day, which lead to great opportunities to harness that energy. For more on this aspect, see Renewable and Non Renewable Energy Sources.

The Earth receives an incredible supply of solar energy. The sun, an average star, is a fusion reactor that has been burning over 4 billion years. It provides enough energy in one minute to supply the world’s energy needs for one year. In one day, it provides more energy than our current population would consume in 27 years. In fact, “The amount of solar radiation striking the earth over a three-day period is equivalent to the energy stored in all fossil energy sources.” Continue Reading Solar Renewable Energy – Is Solar Energy Renewable and Can it Meet our Energy Needs?

Environmental Technology Aspects

Environmental technology, or commonly referred to as envirotech, is also known as green technology, or greentech for short, and can also be termed clean technology, or cleantech for short is defined as the application of one or more of the following; environmental science, green chemistry, environmental monitoring and electronic devices which either monitor, model or conserve the natural environment and resources, and to minimize the negative impacts of human interactions with the environment. The term can also be used to describe sustainable or renewable energy generation technologies such as Photovoltaic’s (solar power), Wind Turbine’s (wind energy), Bioreactors, and other clean or renewable energy technologies. Sustainable development is at the core of environmental technologies. The term environmental technologies is also used to describe a class of electronic devices that can promote sustainable management of resources.

Currently we have wasteful energy policies, an overuse of natural resources, water supply shortages, man-made global climate change, and deforestation on massive scales are just some of the current issues experts say that we need to be address for humans as a species to achieve sustainable living on this planet. By the year 2025, an estimated addition of 2.9 billion people will strain already strained water supplies, and the world’s energy needs will go up by as much as 60 percent by 2030, according to the United Nations so environmental technology will play a crucial role in our maintaining a sustainable balance.

Biomass Energy: What are the Biomass Advantages and the Biomass Disadvantages

When it comes to biomass energy, of course there are biomass advantages and biomass disadvantages. There are distinct good and bad qualities of using this alternative fuel for energy. There are several differing opinions of course, some of which rest upon financial considerations and may be biased, so we will try and eliminate all the biased schools of thought on this hot topic.

Biomass Energy Advantages and Disadvantages

Biomass Advantages

1.) When this is used as a fuel, it reduces the need for fossil fuels for the production of heat, steam, and electricity for the grid, including residential, industrial and agricultural uses.

2.) This fuel is one of the most abundant resources in the world, and it is always available and can be reproduced, seeing that it is a renewable energy source. With proper conservation practices, any plants, shrubs or trees that are harvested to produce energy can be replaced over a period of time.
