Indonesia, which is a tropical country, has a very large potential for solar energy because of its area that stretches across the equator, with a radiation magnitude of 4.80 kWh / m2 / day or equivalent to 112,000 GWp. On the other hand, the earth receives solar power of 1.74 x 1017 W / hour and about 1-2% of it is converted into wind energy. However, from the total energy potential, Indonesia has only utilized around 10 MWp for solar energy and not much different, wind energy, whose utilization is planned to reach 250 MW in 2025, has only been utilized around 1 MW of the total existing potential. With this potential, to be able to supply additional power and help save energy for existing facilities in the building, a Prototype of Solar Panel Hybird and Vertical Axis Wind Turbine was created. The design of this prototype is a combination of savonious type turbines and solar panels, where the use of this type of turbine is because it can rotate at low wind speeds (low wind velocity) and its construction is very simple.

In this paper, experiments that can be introduced to Clean Energy Systems classes are described. The experiments investigate the effect of power characteristics (temperature, shade and tilt angle) on solar panel electricity production. Solar cell efficiency is the ratio of the electrical output of a solar cell to the incident energy in the form of sunlight. The energy conversion efficiency of a solar cell is the percentage of the solar energy to which the cell is exposed that is converted into electrical energy. Extreme temperatures can cause a decrease in solar panel’s power output and airstream can dissipate the heat and bring the solar panel to its normal operating condition. Solar panel efficiency is undesirably affected by heat and improved with introducing cooler medium. As well as heat, solar panel loses its power when a part of it is shaded by trees or surrounding buildings. Before solar panel systems are designed for homes, usually a detailed shading analysis of the roof is conducted to reveal its patterns of shade and sunlight throughout the year. By the same manner, how solar panels react to the direct and indirect rays from the sun in order to produce electricity is examined through experiments. Voltage, current and power flowing into a resistor are measured when the angle of the solar panel relative to the light source is changed. The tilt angles to the electrical measurements are linked to the differences in electrical generation. Students can perform experimental procedures explained here and gain the conceptual understanding of the Solar Energy better. The investigations require student explanation of the question, method, display of data with the critical response from peers.

Prototype Design

Indonesia is a tropical country, because its area that crosses the equator has enormous solar potential, with a radiation magnitude of 4.80 kWh / m2 / day / day or equivalent to 112,000 GWp. Meanwhile, the solar energy received by the earth is 1.74 x 1017 W / hour, of which about 1-2% is converted into wind energy. However, in terms of total energy potential, Indonesia only uses around 10 MWp of solar energy, the difference is that wind energy which is planned to reach 250 MW in 2025 only uses 1 MW of the total potential. Skyscrapers are places with enormous wind energy potential. Because if the height exceeds 150 m, the reference point of the building can be called a skyscraper, which will cause high wind speed at the top of the building. This phenomenon is caused by the influence of the friction force which suppresses the wind speed, therefore the higher the position, the higher the wind speed. With this potential, to provide additional power and help save energy in existing facilities in the building, a smart photovoltaic and vertical turbine prototype design was created. The prototype design is a combination of weathered turbines and solar panels, the reason for using this type of turbine is because it can rotate at low wind speed (low wind speed) and has a very simple structure. In addition, because it uses a vertical shaft, the generator and gearbox can be placed close to the ground, making maintenance easier. The working principle of this prototype is designed to use a turbine to convert wind energy on the roof of the building into electrical energy, then mix it with electrical energy converted from solar energy by solar panels, so that electrical energy will be more optimal.

As two super powers in energy consumption and carbon emission, the United States and China have been striving to develop clean energy in recent years. In this paper, we study the international competitiveness and potential for trade cooperation in clean energy between the two countries. This paper reveals that the United States has comparative advantages in terms of biomass energy and nuclear power, while China has comparative advantages in terms of solar energy and wind energy. The two countries have a strong complementarity in solar energy, biomass energy and nuclear energy with exporting from the United States and importing from China. In solar energy and wind energy a strong complementarity has been formed with exporting from China and importing into the United States. So the two countries have a strong potential for cooperation. Meanwhile, the potential trade cooperation is enhancing with the United States accelerating the development and exportation in natural gas. Therefore, the two countries have a strong trade complementarity on clear energy and a strong potential for cooperation in general. At the same time, the VCR model is built based on the clean energy Trade Complementary Index(TCIc and TCIu) between the United States and China. It can be found that the clean energy trade cooperation helps to curb CO2 emissions and promotes the GDP growth in the United States. However, China is in the early stage of clean energy development, the cooperation would cause a decline of GDP in China.

The deserts of Rajasthan have long been known for their spare beauty and their intense sunshine. Now that sun is being turned into a surge of solar power expansion that may one day power not just Rajasthan but a wide swath of India with clean energy. Rajasthan, with its 300 days a year of sunshine and relatively cheap desert land, has set a goal even more ambitious than Indias. In this years state budget, the newly formed state government announced it hoped to install 25,000 megawatts of solar energy in the state within the next five years, and infrastructure to transmit that power to the national grid. Rajasthan is no newcomer to renewable energy. Since the 1990s, the state has been home to a range of wind energy projects, with about 2,800 megawatts of wind capacity now installed, out of an estimated potential capacity of 5,000 megawatts. Altogether wind power in Rajasthan accounts for about 13 percent of Indias wind energy production. But Rajasthans Great Indian Thar Desert, the test site for Indias first underground explosion of a nuclear weapon 15 years ago, may now help make India a solar power as well. The desert set in Rajasthans largest district Jaisalmer, near the border with Pakistan, it is a place of sand dunes and shrub thickets – but also, increasingly, solar installations that could help change the character of Indias energy development. India committed at the U.N. Framework Convention on Climate Change negotiations in Copenhagen in 2009 to reduce its climate-changing emissions, per unit of GDP, by 20 to 25 percent by 2020, compared to 2005 levels. The country is currently the worlds seventh largest emitter of global warming pollution and the fifth biggest producer of emissions from burning fossil fuels. Sixty-eight percent of those emissions from fossil fuel use come from creating energy for the worlds second most populous country, according to Indias energy ministry. Today the country has 2.28 million megawatts of power generating capacity, and about 12.4 percent of that comes from renewable energy. Of the 2,632 megawatts of solar power now installed in India, Rajasthan so far has only 730 megawatts, putting it in second place behind the state of Gujarat, with 916 megawatts, according to Indias Ministry of New and Renewable Energy. But Rajasthan, Indias largest state and 60 percent covered by sunny desert, is now attracting the worlds interest as a solar hotspot. Around 1 lakh (100,000) square kilometers of barren land is available in the northwest arid belt of the state at cheaper rates that could be utilized for large scale solar projects. The government is formulating the policy to harness the enormous solar potential of the region to meet the countrys growing energy requirements. Besides large solar installations, the government is studying the possibility of grid-connected rooftop solar photovoltaic units for households. The Solar Energy Corporation of India estimates that 130 million homes could potentially be equipped with the units, creating 25,000 megawatts of generating capacity. said Alok, Rajasthans Energy Secretary.
