How do we make and use electricity?

TweetAlmost all of the Planet’s electric power is produced by rotating electrical machines. Electric machines are electromechanical energy converters. Generators convert mechanical energy into electrical energy and motors convert electrical energy into mechanical energy. Approximately 70% of electrical energy is … Continue reading

What is electricity?

TweetAt its simplest electricity is an energy. It is useful to civilisation because it can be efficiently generated, transferred long distances, subdivided and used to power a myriad of machines. It is created by expending another energy (e.g. steam, solar … Continue reading

efficiency

TweetTerraintegra’s use of the word “efficient” or “efficiency” describes the conversion efficiency of energy. This can be described as the ratio between the useful production of a technology as against its required energy input. The useful output may be mechanical … Continue reading

capacity factor

TweetCapacity factor gives the ratio of the actual output of an energy production technology over a period of time as against its output if it had operated at full its full nameplate capacity constantly. Capacity factor is calculated by dividing … Continue reading

nameplate capacity

TweetNameplate (or Nominal) capacity describes the maximum output of an energy producing technology. Most technologies are described in terms of nameplate capacity. However, Nameplate Capacity can cause confusion and at times be misleading. This is especially true when describing alternative … Continue reading

equilibrium

TweetEquilibrium describes the maintaining of a balance between opposing forces and needs. The Planet maintains an environmental equilibrium between incoming solar energy and its eco-system’s energy consumption. A change to this equilibrium can only be incremental so as to allow … Continue reading

energy positive solutions

TweetTerraintegra describes a technology as being energy positive when, taking all relevant factors into account, the energy output does not deplete planet resources or increase planet stress. A biofuel like ethanol may not be energy positive if it consumes fossil … Continue reading

socio-environmental solutions

TweetSocio-environmentalism is concerned with the interrelationship between society and its surrounding environment. Terraintegra seeks to promote harmonic inter-reaction between a society and its environment by promoting socio-environmental solutions. Society needs energy, food, water and enjoyment from its environment. The environment … Continue reading

independent

TweetObvious but very important in the environmental sector is independence to act, think, criticise and support ‘true alternative energy production’ and ‘true energy conservation’ technologies. Without Government or Academic funding Terraintegra is free of sponsorship and has no hidden agenda.

‘true energy conservation’

TweetAll energy, regardless of its origin is a valuable resource. Its waste means inevitable replacement and possible depletion of Planet resources. From cars to fridges, passive homes to farms, energy can be used with greater efficiency.
