working principle of geothermal energy sources
Geothermal heat pumps that are also often referred to as the earth-coupled, water-source, or ground source heat pumps have been in use for almost 70 years now, starting from 1940s. These pumps use the moderate temperature in the ground for both heating and cooling. The temperature below the earth’s surface remains at a relatively constant temperature throughout the whole year, usually in range between 45 F(7 C) to 75 F(21 C), which means that during the winter ground temperature is warmer than the air, and therefore is used for heating, and during the summer the ground temperature is colder …
There is much talk about climate change, and the search for viable renewable energy sources. Everyone knows about the likes of solar, wind and wave power. But fewer have heard of geothermal, or know how does geothermal energy work. So here are some geothermal energy facts, which may help you understand the benefits and restrictions of geothermal energy.
How Does Geothermal Energy Work
Introduction to solar, wind and geothermal energy:
Image showing Renewable energy resources
Renewable energy comes from natural resources like sunlight, tides, wind, rain and geothermal heat. Three major renewable energy resources are wind power, solar energy and geothermal energy. Advantage of renewable energy is that …
Georgia – Energy tax credit, solar rebates and incentives Georgia residential solar energy incentives Clean energy tax credit
The clean energy tax credit gives Georgia residents a 35% credit towards the total cost of installation and equipment.
- The credit listings are as follows:
- $2,000 credit limit for geothermal heat pumps
- $2,500 credit limit for domestic solar water heating
- $10,500 credit limit for photovoltaic and wind energy systems.
In order to claim this credit, homeowners must make sure that all equipment and installation has met …
What are the advantages and Disadvantages of Using Green Energy Sources?
Nowadays, we are at this time aware of the aftermath of global warming. Luckily, it isn’t too late and we will be able to still vary which explains why many are pushing for green energy sources.
The benefit of using green energy sources is clean so it is unpolluted so it doesn’t emit anything harmful into the air which has an effect on the atmosphere. It is also renewable which suggests we will never run out of it not like oil which is expected to dry up in 10 years or so.
Though green energy facilities are dear …
Renewable Energy Sources
As people become more conscious about preserving the environment and maintaining a healthy lifestyle, better alternatives are being developed. This holds true in terms of the worlds energy usage. This is the reason behind the growing popularity of alternative and renewable energy sources today.
What is Renewable Energy? Renewable energy means that it can be easily replenished in a short span of time. This is because sources of this type of energy are in abundant supply and are …

Energy Sources and Use
To distinguish between renewable and nonrenewable sources of energy; to investigate a variety of renewable energy resources and compare the benefits and drawbacks of each.
Students will use Internet resources to investigate and compare …
… I was watching a TV programme, where panelists were debating safe, sustainable and clean sources of energy, in light of the disaster in Fukushima. Wind and tidal sources of energy were the only alternatives taken seriously by half of the panelists, while the other half thought that nuclear energy is the only way forward – biomass sources of energy weren’t even mentioned. Maybe this was because the panel did not include any scientists / environmentalists.
From my observations of the literature I come across daily, while screening for the CAB Abstracts database, there are other more serious contenders to nuclear energy, besides wind and sea tides. There are a lot of …
In today’s world, there are several sources for electricity, and debates continue as to which one we should use.
Coal was used in the early days, but the argument against that is it’s dirty and is bad for the environment.
Oil is extremely popular, and likely the most controversial. There are areas that have an abundance supply of it, but some don’t want to drill there because, like coal, they say it’s bad for the environment.
Another traditional source is wind-powered …
Possible Future Energy Sources
The word “energy” fills the pages of this book, and many forms of energy are described in previous chapters. Energy is, however, really a very tricky and difficult term to define exactly, even for students who have studied physics and engineering for many years. While it is very useful to think of energy as something that can flow like a river from one thing to another, or be stored in a battery, energy really isn’t a “thing” at all. Energy does not exist by the gallon or liter, but a gallon or liter of gasoline has a certain amount of energy, an ability to flow through …
