Geothermal as an Alternative Energy

Geothermal energy means using the stored heat from the earth. Geothermal energy is one  of alternative energy. The core of our planet is too hot that its temperature is estimated to reach 500 C (9.932 F). Thus the distance of 3 meters around the top of the earth's surface temperature is held constant near 10-16 Celsius (50-60 F) every year. With a wide variety of geological processes, then in some places even higher temperatures can be found.
 
Utilizing geothermal energy for work

When the geothermal sources near the surface, the hot water that can be streamed directly to a few places that require heat. This is one way of utilization of geothermal energy to heat their homes, to heat greenhouses and even melt snow on the road.

Hydrogen as an Alternative Energy Source

Latest of this century, fossil fuels became the only one source of energy in the world. Lots of parties fight to take over the primary source producers of energy that cause damage to this world.

Fossil energy use in large scale, especially in the last century, we are faced with various problems. When Fossil was burned to produce energy, fossil fuels release carbon into the air. This causes the release of carbon pollution and damage the ozone layer, which makes the earth we inhabit is getting hot. Continued increase carbon from burning fossil fuels is causing global warming phenomenon.

How to Make Biodiesel from Jathropha curcas

Biodiesel as an Alternative Fuel subtitute. Biodiesel generally can be defined as the fuel from the vegetable, the most likely development for energy substitute is biodiesel (from palm oil and jatropha curcas) as a substitute for diesel and bioethanol (from cassava) as a substitute for gasoline.

How to Make Biodiesel from Jatropha curcas

Jatropha curcas is a shrub of the family Euphorbiaceae. Within five months of drought-resistant plants is starting to bear fruit, full productive at the age of five years, and  his working life reached 50 years.

Biodiesel

Biodiesel is one  of alternative energy being developed. Biodiesel is a fuel for diesel engine  in the form of ester alkhyl or alkhyl fatty acids (usually methyl ester) are made from vegetable oils through a process of esterification. The term biodiesel is identical to the pure fuel. Biodiesel mixture (BXX) as much as XX `% biodiesel mixed with diesel fuel some 1-XX%

Steam Power Plant

FUNCTION

Steam power plant is a type of thermal power plant that is widely used, as it has high efficiency, so as to generate electrical energy economically. Steam power plant is energy conversion machine that converts chemical energy into electrical energy fuel. The process of converting the energy in Steam power plant takes place through three stages, namely:
First, the chemical energy in the fuel is converted into thermal energy in the form of water vapor that has a high pressure and temperature.
Second, the heat energy of water vapor is converted into mechanical energy in the form of round.
Third, the mechanical energy is converted into electrical energy
