Solar power energy systems are not inexpensive. That said it's important to compare them within context of other types of home improvement projects. Home buyers and realtors view a solar photovoltaic or solar hot water heating system as a significant value-added improvement – similar to adding a deck or remodeling your kitchen. Plus unlike a deck or kitchen remodel, you also gain one-up on your power bills. Here are some foolproof ways to estimate the cost of a solar photovoltaic or solar thermal system and to figure out if a solar energy system makes sense for you.
Six Easy Steps To Estimate Cost of a Solar Power System
Solar power energy systems are not inexpensive. That said it's important to compare them within context of other types of home improvement projects. Home buyers and realtors view a solar photovoltaic or solar hot water heating system as a significant value-added improvement – similar to adding a deck or remodeling your kitchen. Plus unlike a deck or kitchen remodel, you also gain one-up on your power bills.
Solar power systems often get an additional financial boost as well: many jurisdictions and utilities across the USA offer attractive financial incentives to drive down the upfront capital costs associated with a solar power system.
Here are some foolproof ways to estimate the cost of a solar photovoltaic or solar thermal system and to figure out if a solar energy system makes sense for you. Let's start with a home photovoltaic (PV) system.
Step 1: Estimate your home's electricity needs
To get started, it's good to have a sense of how much electricity you use. You'll have a better point for comparison if you find out how many kilowatt hours (kWh) you use per day, per month, per year. Your utility bill should include that information.
Of course, the utility bill will also display your costs and many utilities include a graph that displays how your monthly energy use/cost varies throughout the year. That helps you estimate where your highest energy use is and at what time of year.
New Home Construction
If you are constructing a new home, then you'll need to estimate your demand based on the type of equipment you plan to install and your home's square footage. The pross call this "your load".
To figure out your anticipated load, create a table to record the watt use for each appliance. Each appliance – be it a water heater, electric light, computer, or refrigerator – should have a nameplate that lists its power rating in watts. Or you can get the information from the manufacturer's website.
Some labels list amperage and voltage only; to obtain watts multiply the two together (amperage x voltage = watts). In another column, record the number of hours each appliance is expected to operate. Then multiple the watts and hours together to estimate watt-hours used per day. Since it's hard to anticipate all electric loads (it may get tedious scouting out every toothbrush and mobile phone cell charger), you might want to add a multiplier of 1.5 to be safe.

Renewable Energy Resources versus Fossil Fuels
Author: Bryan Wong
In modern western world the demand for energy has increased dramatically in the past century and it will grow even further and harder in the near future than ever before. The need for energy rises with upcoming markets that also need more energy. Energy is needed for cars, buses, and other means of transportation, but also to run our appliances and provides us light. Energy is also important for our safety. At night or in the dark a lot can be stolen without proper lightning. Energy is therefore needed for our development and safety.
The way we use energy today comes from knowledge that has it's foundations in the past century and before. Great men like Newton and Philips have set the path for us today to make proper use of energy. The sources which we use for our energy demand are known as non-renewable energy resources. These sources will be discussed here in the article.
Definition of Non-Renewable Energy Resources
The name really explains it very well. Non-renewable energy resources are natural resources that cannot be recycled or re-grown. These natural resources are fossil fuels like coal, petroleum, and natural gas. It also includes mined resources such as the elements used in the production of electricity (uranium and plutonium, for instance). These resources replenish itself in a quicker rate.
Fossil fuels are very versatile. One of their functions is to generate electricity. In order to generate electricity, fossil fuels are burned through the process of combustion. The energy produced from the combustion process is used to power a turbine. The turbine is responsible for the conversion of energy produced from combusted fossil fuels into electricity.
Coal
Coal is one the most used fossil fuels. It is consider too be the most important energy source to produce electricity. The U.S. produces 50% of its energy supply through the combustion of coal. The coal itself is a brownish-black sedimentary rock which contains carbon and other assorted elements. It is extracted from the ground through underground mining or open-pit mining.
Natural Gas
Natural gas is also used to produce electricity. The electricity is produced through steam turbines and gas turbines. Because the gas contains methane the combustion emits less harmful gasses that have a negative effect on global warming. Thus natural gasses are better for the environment compared to petroleum and coal.
There is also another use for it and that is as fuel for cars. It is much cheaper that gasoline and produces less harmful gasses. The disadvantage of running your car on natural gas is that you need more fuel compared to gasoline and the car needs more maintenance. In countries like Argentina, Brazil, Pakistan, Italy, The Netherlands and India it is used as a fuel for cars.
Crude oil
This fuel is the most talk about for the past year(s). The prices for crude oil have gone through the roof and will be rising even more. The demand is increasing while there is less crude oil available. The term black gold is now more applicable than ever before.The oil itself is very think in consistency and has a dark brown or greenish colour characteristic. It is a complex mixture of different hydrocarbons. Crude oil or petroleum has various uses. It can be used as fuel or cars and different industrial machines. It is also used as a raw material for products like plastics, solvents, fertilizers and pesticides. Although the need for crude oil is high and the demand is rising the available crude oil is decreasing. That leaves us no other option than to look for alternatives.
Non-renewable energy plays a very important role in our daily lives. Non-renewable energy will be needed today and in the future. Because this energy source cannot be recycled or re-grown the reserves are limited. The consequences of the shortages of fossil fuels are experienced today and tomorrow. We will need to use these fossil fuels wisely and will need to shift our focus to other renewable energy source. These are the sources that we need to focus on today and years to come.
