Geothermal Energy GenerationWhile the temperature of the air around you could variety from under zero to above a hundred over the course of a year, the temperature of the ground beneath remains fairly steady all year extended. Geo-thermal systems tap into that consistency to move the ground’s heat indoors in the winter, and distribute its coolness in the summer.

As quickly growing economies seek to safe steady energy supplies, Renewable Power (RE) becomes undoubtedly the panacea. In Nigeria, the government and the people heavily rely on fossil fuel to create power, regardless of plethora natural resources that abound in the nation which when correctly harnessed will safe stable power supplies that will not only be sustainable and uninterrupted, but will impact positively on the environment.

The Philippines are at the moment the regions top country in geothermal energy production. The installed capacity in the nation reaches 1.900 MW, which is the second largest in the globe. The United States hold the primacy with 3.000 MW of installed capacity. The two countries together with Mexico, Italy and Indonesia account for 75% of the world’s geothermal electrical energy. Geothermal energy is mainly applied for heating.

Mike Kaleikini, senior director of Hawaiian Affairs for Ormat Technologies, the parent company of PGV, greeted me in July at his workplace on the PGV compound. It is a low, wooden, prefab structure that can be moved in case of seismic occasion or volcanic emergency. HELCO essential that bids on the new geothermal energy generation be kept secret, so Kaleikini would neither confirm nor deny if PGV was a bidder. But, in the past, Ormat has advocated for geothermal expansion, so it appears likely that the corporation was among the six bidders for the new project.

Geothermal energy is contained in the heated rocks and fluid that fill the fractures and pores inside the earth’s crust. It can be harvested in two strategies, direct use of hot water or steam for space heating or industrial use such as aquaculture, thermal baths and hot springs, and to power electricity generation plants. Direct use is confined to low temperatures, commonly below 150o C whereas, energy generation employs higher temperature sources more than 150o C. 80 countries have created direct use of geothermal power and 20 exploit geothermal power for energy generation. Direct low-temperature use employs about twice the power capacity as is applied for power generation.
