## Surplus Alternative Energy and Blockchain

3600Electricity energy

A common problem with renewable energy is this. There is energy production, but it is not always possible to use it, there is no constant consumer.

There are two options. Either put the battery in the battery to accumulate and recycle as needed, or find a constant load that can at any time dispose of excess (and with benefit).

With today's battery prices, the first option looks utopian, they will never pay back.

It is decided to try to set up a mining farm that, by consuming surplus energy from the alternative, not only monetises this energy but also produces little profit. That is figuratively speaking, consuming 1 kW of energy produces monetary equivalent of 1.2 kW. It should be noted that it all depends on the electricity tariff and the constantly floating cryptocurrency exchange (both ordinary and ordinary money).

Since the non-battery option was chosen, a grid-inverter is usually used.

The advantage of this approach, compared to the battery, is the following. The equipment does not lose its characteristics over time, the equipment pays off for a year and a half (depending on tariffs see above), monetized energy (can be used-pay anywhere), equipment is constantly ready to use surplus electricity.

Another fat plus is that when the farm is running, all the energy it supplies is converted into heat, and for example, it is possible to heat the technical room.

Cons. There is no autonomy when disconnecting external power supply, for some it is not critical. You need to understand the mining of cryptocurrency and look for profitable currencies for mining.

The experiment was conducted for almost six months to determine the viability of this variant.

4 used of graphics cards were purchased and a small farm was built on the basis of a home computer.

In the end, even without an alternative (just from the socket), the farm pays for its consumption and consumption at home. In the presence of an alternative, of course, everything is the same, but even for bread and butter remains.

They gave a couple of digits.

Suppose an alternative energy source generates 600 watts of excess.

When using a 100 Ah battery (and as recommended by manufacturers), there must be a minimum of 5 batteries to maximize their life.

10Ah * 12 * 5 = 600W (charge-discharge).

The approximate price of these batteries (good non-automotive ones) is about $165 apiece. That is$825 that will never come back to us - money for the wind.

Now let's take a video card farm (from an experiment in particular). 4 cards consume 600 watts, that is, the charge mode is the same as a battery, but the accumulated money can be used from the socket at any power, although 3 kW load. This is another little treat.

At the same time, if the calculations are correct, then these cards will pay off completely, at the moment about 30% of expenses have already paid off.

BU cards were purchased at $95, and over time they could be sold at residual value.$95 * 4 = $380 +$100 (Extra Cost: Frame, Power Supply, and Other Trivia).

By and large, something like a green tariff came out, which in a big country of nanotechnology is unclear when it will or will be at all.

Another point, it is believed that video cards are killed and do not serve long when mining. Of course, if the king in the head is impossible and the anvil to break. But with proper tuning, the mining cards serve longer and experience less load than when playing any kind of tank shooting, etc.

The idea is not new, there is an opinion that many use it. Do not take this as an option to make money, the purpose of this approach is to use unnecessarily.
