FAQ
What is digital transformation in oil and gas?
Â
Environmental and geopolitical developments are forcing oil and gas corporations to restructure their businesses and make new plans for the future of their enterprises. The most promising trend is a digital transformation or the process of implementing digital technologies to optimise the main technological processes for oil and gas production, storage, and transportation.
Â
What is solar energy systems engineering?
Â
The fundamental idea behind solar energy systems is that solar panels use the photovoltaic effect to convert solar energy, or sunshine, into DC. The DC energy can subsequently be transformed into AC energy or stored in the battery.
In countries with hot climates, this approach makes it possible to create solar water pumps or solar air conditioners. Utilizing them lessens the expense of energy use and its negative effects on the environment.
What are some examples of green technology?
Â
There are several types of green technology:
- solar power (solar air conditioning, solar charger, solar inverter);
- wind power (windmill, wind-powered wheels);
- bioenergy (system for biomass production);
- geothermal energy (geothermal turbine, geothermal generator).
