Solar Thermal Heat for Water and Buildings

The solar thermal industry has used low-tech technology until relatively recently and been largely concerned with small domestic and building applications for heating space or water, or cooking. However, the industry is now taking a more sophisticated direction and progressing to higher-tech applications involving relatively large electricity generation projects in a number of countries. Some […]

Metering Trends

Sub-Metering A largely untapped market, Sub-Metering is set to grow substantially in the coming years in various sectors. Though technology is already widespread in use in water and heat metering applications, electricity is becoming a growing market as well. The case for Sub-Metering is made in different types of markets with large urban built-up areas […]

Natural Gas

Unproved probable reserves Probable reserves are those unproved reserves which analysis of geological and engineering data suggests are more likely than not to be recoverable. In this context, when probabilistic methods are used, there should be at least a 50% probability that the quantities actually recovered will equal or exceed the sum of estimated proved […]

The cost of electricity in the future, the price of renewable energy

The cost of electricity is a complex calculation. Using a number of assumptions it is possible to calculate the cost of producing electricity in a fixed situation but there are still external variables, especially in a lifetime cost calculation, which an owner has to evaluate with additional risk and sensitivity analysis. These include political factors […]

Renewable Energy

Most energy sources can be consumed in two ways, directly and indirectly when converted to another form of energy. For example, wood can be burned directly as a primary energy source to heat space, or it can be burned to produce heat to generate electricity, a secondary energy source. Likewise, geothermal energy can be used […]
