The world we live in, is becoming more and more dependent on electrical energy, which, sadly, still heavily relies on outdated techniques involving the burning of fossil fuels. Fortunately, more and more people are accepting the fact that this system simply isn’t sustainable in the longer-run. Even if air pollution wasn’t a huge factor, the shortage of these resources is something that is bound to happen in the nearest future, and it would pose an impassable obstacle towards the future growth of mankind. Hence, importance of renewable energy is such an important trend for the future of mankind. At present, net AC meters are available for measurement of four quadrant energy, which is used at output of both on grid and off grid solar inverter. This meter can measure both, energy fed into the grid and energy utilize from the grid. However Energy generated by solar panel cannot be measured directly. Even in off grid inverter the present net meter cannot measure energy generated by solar panel. In case of DC micro grid, where DC energy is used/ consumed directly by the load, the present net meter cannot be used as they can be used in AC energy measurement only. With the launch and implementation of national energy saving and emission reduction policies in relation to distributed power supply by renewable power generation, the DC energy metering technology will become an inevitable trend, breaking the landscape dominated by AC in the field of electric energy metering. This paper describes introduction, block diagram [1], Hardware and software description for development of dc energy meter.

The goal of power sector in Nigeria is to efficiently and reliably transmit electrical power to all parts of the country which are made up of thirty-six states of the federation and the federal capital territory. The constituents of electrical power system are the generation, transmission, distribution and the utilization of electrical energy. There is gross power imbalance between the generation and the required power demand which has culminated into a defective economy in the last three decades. This paper therefore examines the power imbalance between the generation and power demand by the consumers and therefore stresses the need to harness the opportunity of renewable energy generation close to the gap between the power generation and power demand. This will help in transmitting and distributing efficient, effective, reliable power to consumers and improve both human and capital development. The availability of renewable energy sources such as sun, wind and small hydro power will be explored for the future of power generation in the country to fill in the gap between power generation and demand in Nigeria

Solar Tracker The generation of power from the reduction of fossil fuels is the biggest challenge for the next half century. The idea of converting solar energy into electrical energy using photovoltaic panels holds its place in the front row compared to other renewable sources. But the continuous change in the relative angle of the sun with reference to the earth reduces the watts delivered by solar panel. Conventional solar panel, fixed with a certain angle, limits their area of exposure from the sun due to rotation of the earth. Output of the solar cells depends on the intensity of the sun and the angle of incidence. To solve this problem, an automatic solar cell is needed, where the Solar Tracker will track the motion of the sun across the sky to ensure that the maximum amount of sunlight strikes the panels throughout the day. By using Light Dependent Resistors, it will navigate the solar panel to get the best angle of exposure of light from the sun.

<span>We have, an overview is presented of the potential future demands and possible supply of solar energy to Iraq. Solar energy, which is clean, unlimited, and environmentally friendly, is presented as a renewable energy resource. Many problems such as CO<sub>2</sub> emissions, industry, human activities, and electricity distribution grids have attracted much attention because of the current state of crude oil production and its prices. Moreover, estimations of solar radiation levels and of the efficiencies of photovoltaics (PVs), concentrated solar power (CSP), and solar chimney towers, have all been investigated. Those systems that combine various sources of energy are called hybrids and they have received much attention in recent decades. The basic features of solar radiation in Iraq are outlined, and the selection of those sites with potential for development of solar plants is based on the local largest solar radiation. Moreover, longitudinal and latitudinal orientation, wind, solar intensity, dust, temperature, rain, humidity, and pollution factors are all considered in the calculation of PV/CSP efficiencies. We know there is an abundance of fossil fuels in Iraq, energy shortages began in 1991 because of the perturbation caused by the full ruin of the country. The obvious renewable energy resource available in Iraq is the solar energy, and its exploitation would provide a means to reduce CO<sub>2</sub> emissions from the burning of fossil fuels and to achieve self-sufficiency of electric energy and export the rest to neighboring countries. Solar energy is becoming increasingly important because of the climatic change in the form of global warming.</span>

In this paper, an attempt is made to answer the question: Can renewable energy sources eventually supply India’s electricity needs in the future? In particular, we examine the total potential of renewable energy sources in India and extent to which they can supply these needs. The estimates made here indicate that even with a frugal per capita electricity need of 2000 kWh/annum and a stabilized population of 1500 million by 2025, India would need to generate approximately 3000 TWh/yr. As opposed to this, a systematic analysis of the information available on all the renewable energy sources indicates that the total potential is only around 1000 TWh/yr. It is concluded that in the future as fossil fuels are exhausted, renewable sources alone will not suffice for meeting India’s needs.
