The basic purpose of active thermal air conditioning is to transfer thermal energy. Traditional compressor-based cooling systems work by releasing thermal energy from the interiors of the home to the exterior. These conventional systems do not utilize the thermal energy (heat) to run the cooling process. Other types of systems like absorption chiller utilize manufactured thermal energy to activate an endothermic air conditioning process.

Working of Active Thermal System

Active Thermal System

Basically there are two main types of thermal cooling systems, these include active and passive. Active cooling systems utilize mechanical tools to perform their functions. On the other hand, passive thermal cooling systems do not utilize any type of mechanical tools. Mechanical tools help in pumping the fluids and blowing air through the cooling unit and also to in and out the home.

Types of Active Thermal Cooling Systems

Most active thermal cooling systems are operated by one of three energy sources. The commonest that is being utilized is gas-fired systems. The gas is a natural gas or propane. The current sources of renewable, energy efficient cooling and heating systems are solar thermal and geothermal systems. Read the full story

The solar power energy is new but it is going to go forward in near future because if its cheapness reliability and environmental benefits.

How Do Solar Panels Work?

How Do Solar Panels Work

The solar panels absorb the sunlight. It is then turned into electricity, which feeds into the utility poles hooked up to PG&E’s massive grid.There are some points to be kept in mind that all commercially available solar panels produce electricity only. That is of course good for running lights, air conditioners, microwave ovens and many other appliances but many appliances in our household are running on other fuels, like oil or natural gas. These are heaters, stoves, etc.

Evaluating The Usage Of Electricity

It is essential to evaluate first the total consumption of electricity of the house. Solar panels do not work after the sun sets. So for consuming electricity after dark you will need a battery storage system. Read the full story

Solar desiccant system works on the solar energy this system is a thermally activated cooling system; it absorbs the solar heat for separation and evaporation of the refrigerant fluid. The desiccant system uses solar-heated air to reproduce desiccants that helps in driving off the warm water in air. The cooled air produced is through different evaporative stages and then finally transferred to different parts of the home.

Solar desiccant an expensive system

Solar desiccant an expensive system

It is not necessary that desiccant system will cool and remove the humidity from the air. Use of the desiccant systems is not very common. The main reason of less use of these systems is that they are more expensive and they work in combination of the heat-driven and natural gas cooling systems.

Working

Solar cooling system operating on the desiccant system can work better in low temperature place than the solar absorption systems. Solar desiccant systems work on the solar thermal energy that is obtained from the rooftop solar collectors. Read the full story

The main reason for higher gas prices are a rise in the prices of crude oil. The prices generally rise when demand exceeds supply. But in some cases, where the political situation of the world is at unrest, Companies buy the gas and gold for future reserves. This sometimes is the cases of high gas prices.

The Seasonal Rise In Prices

The Seasonal Rise In Prices

Gas prices usually rise in summer season where the traveling doubles than usual travelling. Every year, it is observed that the gas prices rise in the mid of the year. Since in summer season, most people want to go to different cities.

How The Rise In Crude Oil Affects Gas Prices

Trading of gasoline, which is primarily sold at the regional market and crude oil, is traded in the global market. The prices of crude oil are necessary in determining the prices of gas because crude oil is a primary raw material which is used in the production of gasoline. The price of crude oil may be accountable for over half the price of a gallon of gasoline.

Reviews On High Gas Prices

Know Your Bill – Shift To Solar Energy

Tags: , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , ,


Pacific Gas & Electric Company is one of the largest of suppliers of a combination of natural gas and electricity in California, United States. This firm is originally based in San Francisco. This company provides electricity to more than 15 million residents over an area of 80000 square Kilometers in Northern & Central California.

Pacific Gas & Electric Company facilitates roughly 9.6 million Electric and Natural Gas consuming customers and is responsible for their needs.

Shift To Solar Energy

However due to increased consumption of energy, a dire need is felt to shift to other modern and sophisticated sources of obtaining energy. Perhaps Solar Power is the answer.

Step towards A Green Future

In the modern world, development requires resources. One of the most significant aspects of the term resources is “Power”. Power can be in the form of labor or monetary assistance. To many this term may simply mean “Power to use”. By that I mean power resources which help us live our lives. Over time many people have become increasingly tired of receiving long and hefty power bills. These bills are extremely hard to pay back and cause many less earning families face problems. To avoid this hustle, simply what you have to do is shift to Solar Power.

What is Solar Power?

Solar Power is the energy obtained by Sun Light. Sunlight can be converted to electrical energy by the use of Photovoltaic Cells. For many people, these terms are extremely confusing and frustrating and some individuals just might cheat you under the pretext of providing you with better and cheaper shift to energy. I will define some of these terms to you beforehand.

Some Terms

Photovoltaic Cells: Also known as Solar Cells is a solid state device which directly converts the Sun Light into Electric Power through the Photovoltaic Cell.

Watt: Watt is an International Unit for measuring the consumption of Power in a certain time.

Kilo Watt: A Thousand Watts

Mega Watt: A Hundred Thousand Watts

Peak Hours: The time when Power consumption is the most.

Net Energy Metering: What remains after the deduction?

-Meet the Mother Of Complications

It is Complicated

These are some of the terms you very often come across while viewing your Electric Bill. After closely monitoring the Electricity bills of 2 of my close friends, I have come to the conclusion that Energy bills are really complicated for those with improper knowledge of these terminologies and they are very hard to pay back at certain times. Many people all over the world are living without the privilege of Electricity.

How Can Solar Power Help?

These people are deprived of perhaps the most basic commodity of life. In such times we are blessed to have access to Electricity plants which provide us Power to use. But would it not be better to shift to a much convenient and environment friendly power resource? Yes it would definitely be. By comparative analyses it is proven that people using PV Cells for generating power are much better than those depending upon local institutions as such PG & E Company.

First of all I will tell to you that if you plan to shift to Solar Power system, you will have to come into agreement with your Local Energy Provider. Like PG & E Company. They gave my friend a rate plan of E1 & E7.  If you choose E1 rate plan, the Company will provide them Power at the same rate and will credit them for every unit extra they produce and give the Company. You will be credited this way.

It Can Save You Money

It Can Save You Money

If you choose the E& package, the `Time You Use` (T.O.U) your energy will determine the bill you receive. That means the Company will charge you more during Peak time and less during Non-peak time. So logically, E7 Package, upon your choosing will require you to install a special meter which will cost you approximately $250 or more and will measure your Peak and Off-Peak hours separately.

The Peak Hours are from “12:00 A.M to 6:00 P.M”. This is the time when you will be earning the most of your money if you have the correct PV Unit installed! So my friends, before they got their Solar Panel Unit installed, received PG & E Company’s Energy Statement or more informally known as a Blue Bill. Read the full story
