Getting to Know Geothermal Based Power Plants

 Indonesia has a very large geothermal potential, which is mostly underdeveloped due to several obstacles.  This has not deterred the government’s attempt in maximizing  available potentials by addressing these obstacles.

With the large amount of available potentials, Indonesia will not only able to fill its electricity demand, but also has the capability to export geothermal-sourced electricity.  Indonesia’s current geothermal potential equals to 28 GW, of which only 1189 MW (4%) has been harnessed.

The Seven Types of Power Problems

Our technological world has become deeply dependent upon the continuous availability of electrical power. In most countries, commercial power is made available via nationwide grids, interconnecting numerous generating stations to the loads. The grid must supply basic national needs of residential, lighting, heating, refrigeration, air conditioning, and transportation as well as critical supply to governmental, industrial, financial, commercial, medical and communications communities. Commercial power literally enables today’s modern world to function at its busy pace. Sophisticated technology has reached deeply into our homes and careers, and with the advent of e-commerce is continually changing the way we interact with the rest of the world.

Problem of Indonesia Renewable Energy Development

Indonesia is a country with enormous energy resource potential. But unfortunately Indonesia still has not able to optimize its resources, especially concerning energy supply to it citizen. Some of Indonesian citizens still do not have access to electricity and the rest of it does not have any guarantee on the availability of energy supply. Sometime we should prepare candle and generator to continue our activity. Not only electricity, in some areas, it is still difficult to obtain gas needed to cook. This problem affects our productivity and it affects our economy. This problem has not been solved until now.

Building a National Electricity Grid can be done with Private, not Public, Money

Washington, DC, September 20, 2010 - The benefits of a truly national electricity grid have been known for years. Advantages include increased reliability and efficiency, as well as the potential to transmit power generated from renewable sources across long distances. Despite the promise of cheap, abundant, and reliable electricity, significant financial and regulatory barriers to the development of a national grid remain.

Chinese Firms Developing Solar Power Plants for Less Than 1 Yuan per kWh?

A recent round of bids for utility-scale solar plants in China broke the 1 Yuan per kWh ($0.15 per kWh) threshold highlighting the government's push for clean energy at all costs.

by Lou Schwartz, China Strategies

The late August round of bids for utility-scale solar power projects in China yielded a new milestone in the economics of solar power in China: a sub-Yuan/kWh price for solar power. To achieve this impressive number, the Chinese government has used the state-owned sector (and particularly enterprises under the direct control of the central government) to help subsidize the price of solar power, to the point where the economics appear to be unsustainable.

ABSTRACT :The increasing human population and rising standard of living hence increase energy demand as well. Electric power is vital requirement for economic and social development. The availability and reliability of sufficient, safe, and affordable electric power are important factors in order to build an economical system of a country that is able to enhance people’s welfare.

From the data of electric energy consumption in Indonesia, most of the electricity used was generated from fossil fueled power stations. These fossil fueled power stations utilize unrenewable natural resources. Conversely, in the same time, the utilization of renewable energy resouces is still less competitive if compared to the utilization of unrenewable energy resources. However, for rural/suburb areas, the technology of electric energy generation from renewable resources is so convenient. In addition, the utilization of the renewable energy resource also helps improving the electrical system, that is usually has low reliability level in those rural areas. The technology that will be implemented has to be cheap, practical, eco-friendly, economically cost, and sustainable.The technology is also supposed to be supportive to the activities of people nearby. One of the suitable technologies is the technology of bioenergy utilization from biomass.

Energy from biomass can be obtained from various methods, one is to utilize the biogas produced from those biomasses. Biomass can be either organic waste or feces. These biowaste are usually unnoticeable and left unprocessed, whereas it is really easy to find these energy resources around us. One of those resources is the human feces. The human fecesis so abundant and easy to find in any settlement. The technology that utilizes conventional biowaste would be more productive if its energy resources be combined with human feces. The combination results sanitation-system-integrated biogas reactor.
