Learn How To Survive Energy Crisis
This is about 1 5th of average for the grid connected American home. Roger and Ana use propane for cooking and water heating. Their 1,300 square foot home is well insulated and equipped with three systems for space heating. First is passive solar from the greenhouse attached to the south side of the house. Second is a wood fire space heater in the house's main room. And third, a propane space heater that's not often needed.
So what's stopping forward progress Why is there a new energy crisis all the time Big business is easy. Nor energy crisis - no big profits. No energy crisis - no new toys (nuclear plants, etc.). Wow, the executives are out of a job the banks are worried is this the end HA HA That leaves the last big, big government. Big government needs the energy crisis. It needs the false idea of international conflict over energy to flex its military , economic and political muscles overseas. It uses the same crisis to stir up people at home with false patriotism and bring about economic, social, and political changes for the furtherment of its own ideals of big government at the expense of all else.
Incidentally, there is another type of inverter called grid-interactive. It is used to feed solar (or other renewable) energy into a grid-connected home and to feed excess energy back onto the utility grid. If such a system does not use batteries for backup storage, it is not independent from the grid, and is not within the scope of this article.

As discussed above, the primary energy equivalent of the annual PV yield can offset some to all of the primary energy (fossil fuels and electricity) needed by a house. In the case of an all-electric house (for example, space heating and DHW supplied by a compression heat pump), the PV yield can be directly compared to the electricity consumption by these technical systems. A sophisticated energy-saving concept is a precondition for such a PV application. Figure 14.1.1 shows the relevance of the PV output for different high-performance housing concepts. The light grey arrows indicate primary energy delivered the dark grey arrows point to the primary energy equivalent of the annual PV yield. The width of each arrow indicates the amount of energy. Except for the stand-alone case, all PV systems are grid connected.
I have been a renewable energy buff since the 1974 energy crisis. Windmachines for generating electrical power always fascinated me. In 1974, I bought a 200 Watt 12 Volt windcharger and installed it on a 35 foot steel tower. It generated a small amount of power for the house. At the time, I had 5 24V aircraft 35 Ampere-hour batteries (wired in series to produce a pack of 130 VDC). The batteries fed a 1kW. rotary converter, 130 VDC in and 120 vac out, which ran the house. The 12V output of the wind charger fed a 12V to 120V, 150 watt Tripplite inverter which in turn fed a rectifier driven by a small auto transformer to boost the voltage up high enough to charge the 130V battery.
My current employment and family concerns dictate that I live in the city within easy commuting distance. However, this serves not to lessen my concern for energy and the environment, but to learn how I, as a grid-connected user, can do better and better. To that end, I make the following observations A) When buying a refrigerator, be sure it has a condenser mounted on the back for natural convection. The fan power and noise is thereby eliminated. We chose a unit manufactured by Gibson. B) Electric resistance stoves and dryers are silly. Since natural gas prices have dropped, it's being burned to run steam turbine generators. Thermodynamically, only 43-46 of the energy available in the fuel gets onto the powerline. The electricity user not only pays for the gas, he she pays for all that expensive (I know I used to work on steam turbines generators a row of blades can get into six figures) power station equipment. Bottom line burn the gas directly in your house if you live in the city...

Within a fuel cell, hydrogen reacts with oxygen - pure or extracted from the air - and induces an ion flux through the electrolyte (usually an ion-porous membrane). Electrical power is generated while water is produced as a main reaction product (see Figure 12.6.1). This high-exothermic electrochemical reaction can be carried out at various temperature levels, depending on the type of cell (see Table 12.6.1). The temperatures together with the waste heat from the reformer have to be considered for applications with combined heat and power use (CHP). The electrochemical reaction under real conditions induces a voltage ranging from 0.6 V to 0.9 V DC per cell. Therefore, cells are stacked (connected in series) to reach a useful voltage. In a high-performance house, the DC current is converted to AC by an inverter, comparable to those developed for PV applications. With the exception of autonomous houses, the systems are grid connected. The so-called 'self-sufficient solar house' in...
