In 2009, the Chávez administration declared a national electric emergency and invested $100 billion US dollars towards solving it. The Chávez administration "distributed million-dollar contracts without bidding that enriched high officials of his government and the works were never built", according to Univision. stated that the government awarded electrical contracts to companies with little experience in the energy sector. Billions of dollars were award. [pdf]
Total energy supply (TES) includes all the energy produced in or imported to a country, minus that which is exported or stored. It represents all the energy required to supply end users in the country.
Several factors have severely hampered Venezuela's energy sector, most notably government mismanagement, international sanctions, and the country's economic crisis.
Considering that in 2016 the Venezuelan total electricity demand was around 18,300 MW there is a significant deficit of 1800 MW , . Table 2, Table 3 present some details of the current advances of the main hydro and thermoelectric on-going projects in Venezuela as well as the investments made for their development.
The Venezuelan energy framework Venezuela plays an important role in global energy markets. Along with the rest of Latin American countries, it has evidenced different stages on its energy evolution. The understanding of some relevant facts about this sector is needed to evaluate current conditions and challenges.
Venezuela's restrictive economic policies (Figure 3) have resulted in a decrease in inflation-adjusted GDP per capita, which has led to a decrease in energy consumption (Figure 4). Venezuela has the refining capacity to meet its domestic demand, but the country’s refineries are in poor condition.
The energy imbalance in Venezuela and the effects on the population. Lack of energy policy programs to introduce renewable energies. Recommendations to implement renewable energy projects. Need for an energy transition towards sustainability.

In , a capacitor is a device that stores by accumulating on two closely spaced surfaces that are insulated from each other. The capacitor was originally known as the condenser, a term still encountered in a few compound names, such as the . It is a with two . Capacitors consist of two parallel plates with equal and opposite charges, creating a uniform electric field directed from the positive to the negative plate. [pdf]
When we find the electric field between the plates of a parallel plate capacitor we assume that the electric field from both plates is E = σ 2ϵ0n.^ E = σ 2 ϵ 0 n. ^
This ability is used in capacitors to store electrical energy by sustaining an electric field. When voltage is applied to a capacitor, a certain amount of positive electric charge (+q) accumulates on one plate of the capacitor, while an equal amount of negative electric charge (-q) accumulates on the other plate of the capacitor. It is defined as:
When an electric potential difference (a voltage) is applied across the terminals of a capacitor, for example when a capacitor is connected across a battery, an electric field develops across the dielectric, causing a net positive charge to collect on one plate and net negative charge to collect on the other plate.
In a simple parallel-plate capacitor, a voltage applied between two conductive plates creates a uniform electric field between those plates. The electric field strength in a capacitor is directly proportional to the voltage applied and inversely proportional to the distance between the plates.
The electric field strength in a capacitor is directly proportional to the voltage applied and inversely proportional to the distance between the plates. This factor limits the maximum rated voltage of a capacitor, since the electric field strength must not exceed the breakdown field strength of the dielectric used in the capacitor.
But in a real capacitor the plates are conducting, and the surface charge density will change on each plate when the other plate is brought closer to it. That is, in the limit that the two plates get brought closer together, all of the charge of each plate must be on a single side.

The price of hydrogen increased to 12.85 euros per kilogram on June 7th, according to H2 Mobility, Germany’s sole operator of hydrogen filling stations. This is the first price rise in ten years, according to the supplier. For long years, the unit price for hydrogen was 9.50 euros per kilo.
Process: Purchasing new hydrogen fuel cell vehicles (HFCVs) involves acquiring vehicles specifically designed and optimised for hydrogen fuel cells. Upfront Purchase Cost: Hydrogen fuel cell buses or trucks currently cost between £250,000 and £350,000 per vehicle, significantly higher than diesel equivalents.

Across all state , diesel trucks are the cheapest to operate, as their TCO ranges from $1.88/mi (Texas) to $2.06/mi (C
Plug Power, an American company that makes both fuel cells and electrolysers (the machines that make green hydrogen when powered by renewable energy), warned in its third-quarter earnings call that the price of hydrogen in California fuel stations had doubled to $30 (£24) per kilogramme and many were running dry.
As a complement to battery electric solutions, hydrogen fuel cells will offer a solution for heavy-duty and long-haul truck transport, where good electrical charging infrastructure is hard to come by or the size of the battery required to power the machine would be too unwieldy.
