The graph delineates the comparison between energy capacity proportion of 2010 and the projections suggested for the year 2050. The parameters mentioned in the graph are, sources of energy and percentage. Overall, a huge difference can be seen for non-renewable and solar energy, whereas the same magnitude of difference is not seen in the other two categories. To begin with, it is evident that the energy capacity in the year 2050 for non-renewable source will be slightly less than half of the percentage in 2010.Next, by a glance at the graph we can observe that there will be a 10% increase in biomass and biofuel source of energy by the year 2050. In comparison to the projection of 2050, we can discover hardly a change of 1% in the bracket of water and geothermal energy in 2010.On the contrary, we can notice a spike in the projection for solar enegry of approximately 30% by the year 2050.This is the largest difference seen on the graph compared to other entities.

The bar diagram compares the energy sources such as Non-renewable energy, biomass & biofuel, water & geothermal and solar energy in 2010 and 2050. The unit of measurement is percentage for references. Overall, It is evident that non-renewable energy was significantly higher percentage when compared to the other energy resources while other sources didn't exceed more than fifty perecentage over the years. To begin with, in 2010, Although production of non-renewable energy had the highest percentage, accounting for 73 % approximately. it had the least energy production from biomass and fuel, with just under 5 %. Similarily, energy capactiy from water & geothermal and solar sources had low production, with just under 15 %. On the other hand, in 2050, Constrastly, it is predicted that solar energy will have the highest energy production, accounting for 39 %. when compared to other sources. with non-renewable energy holds the second highest energy production with 35 %. Moreover, energy sources from water & geothermal sources will be slightly increased from 11% in 2010 to 12% in 2050.

The bar graph differentiates between the percentage of energy volume (Non Renewable, Biomass and biofuel, Water and geothermal, Solar) in the year 2010 and the estimate put together for it for the year 2050. Overall, the capacity was highest for Non-renewable energy, accounting for 75%, during 2010. According to the assumption, Solar energy is going to equate to almost 40% by 2050. For the year 2010, it can be noticed in the chart that apart from the extensive use of Non-renewable energy, the use of water and geothermal is only 12%, followed by solar at 10%, and then biomass and biofuel at 5%. In contrast, for 2050, the use of non renewable energy is expected to decline, amounting to 35%, whereas the usage of biomass and biofuel will double. Furthermore, water and geothermal energy's utility will not witness major change. This will remain around 12-13%. However, Solar energy's capacity is supposed to gain substantially by approximately four times.

The given bar graph illustrates the comparison between the proportion of energy capacity in 2010 with the projections made for to 2050 for four different sources of energy. The unit measured is in percentage of energy. Overall, it can be observed that percentage of energy capacity is gradually decreasing for the sources of energy except solar energy which is predicted to reach its peak by 2050.However, non-renewable energy still has the highest proportion of energy capacity. In 2010, non-renewable source of energy had the highest capacity, almost three fourth of total energy capacity.Following that, the water and geothermal energy source comprises around 11% of energy. The solar energy and biomass and biofuel energy are found quite less which is 9% and 5% respectively. On the other hand, the prediction for 2050 are showcase that, there will be significant rise in the solar energy capacity which will around 39%. However, on the contrary, there will be drastical drop in the energy capacity of non-renewable source of energy comprising around one third of total energy capacity. Additionally, similar energy capacity is being predicted for energy sources like biomass and biofuel and water and geothermal which is 14%.

The illustration provides insights on the distribution of energy capacity among 4 categories namely, non-renewable energy, biomass and biofuel, water and geothermal and solar energy in the year 2010 and foresees the figures for the year 2050. Overall, non-renewable energy had the highest energy storage in 2010 with drastically lower projections made for 2050. On the other hand, solar with a significantly lower energy capacity in 2010, was predicted to peak in 2050. In 2010, non-renewable energy possessed 75% capacity of energy, which was foreseen to decline by 40% in the next 40 years. Biomass and biofuel reported the lowest reserves of energy with 5% in 2010, but the predicted figures were expected to go up by 7% in 2050. Water and geothermal sources of energy were predicted to have approximately similar energy capacity in both 2010 and in 2050 with 11 and 12% respectively. Although, solar recorded only 8% of energy capacity in 2010, it was aimed at achieving 38% energy reserves by 2050, significantly higher than its 2010 reserve.

The bar graph represents the amount of energy generating capacity for various sources in the year 2010 and 2050 with the proportion measured in percentage . Overall , it can be visualised that there will be an increase in capacity of renewable sources of energy with a significant decrease in non- renewable energy by the year 2050 . In the year 2010, it is evident that non- renewable sources were ranking top with above 70% of all the sources of energy . However, this trend will change drastically by 2050 projection with a sharp decline to about almost 35% points that is half of the value in 2010. On the other hand, solar energy source has shown a sudden rise to almost 40% by 2050 from almost near to 10% in the year 2010 for generating energy . In addition to this, biomass and biofuel hover with approximately around 10% in the year 2010 to around 15% in the year 2050 of all the sources . Furthermore , water and geothermal energy sources depicts a stable period of energy capacity with about 10% of all the sources in both the years. Hence, it can be concluded that the proportion of energy capacity will be increasing for renewable source like solar rather than non-renewable source in the year 2050 as predicted .

The graph compares the energy capacity distribution in 2010 with projections for 2050, highlighting significant shifts in energy sources over the 40-year period. In 2010, fossil fuels such as coal, oil, and natural gas accounted for the largest share of energy capacity, but their dominance is expected to decrease substantially by 2050 due to a global shift toward sustainable practices. Renewable energy sources, particularly solar and wind power, are projected to experience dramatic growth, with solar energy becoming a major contributor. Wind energy also shows significant expansion, while hydropower maintains a steady presence. Nuclear energy's proportion remains relatively stable, indicating its continued, albeit limited, role in the energy mix. Additionally, other sources like bioenergy and geothermal energy are anticipated to grow modestly. Overall, the graph underscores a transition from fossil fuels to cleaner, renewable energy sources, reflecting ongoing efforts to combat climate change and promote environmental sustainability.

The bar graph demonstrates the energy capacity statistics for 2010, compared with future expectations after 40 years (2050). In particular, four significant sources of energy are mentioned: Non-renewable energy, Biomass and biofuel, Water and geothermal and Solar. The data is measured in percentage. Overall, a drastic decline is expected in non-generatable sources of energy. Meanwhile, the other three resources will improve in the coming decades . Firstly, in 2010, the capacity of non-renewable energy sources was markedly high at 75%, followed by hydro-geo-thermal sources acquiring around 12%. Although a limited contribution was offered by fossil fuels and energy generated through sunlight, 5% and 8% respectively. After four decades, in 2050, solar power will capacitate more than other sources, precisely about 38% of the total. However, finite resources will lead to the second position by contributing 35%. Surprisingly, energy production through biomass and biofuels will increase by 12%, and water and geothermal production will rise slightly.

The bar graph illustrates the percentage of energy generated using various sources such as Non-renewable energy, Biomass and biofuel, solar, and water and geothermal in year 2010 and projection made for to 2050. Overall, Non-renewable energy dominated energy production in 2010 but declined significantly in 2025. Biomass and biofuels, water and geothermal, and solar are forecasted in an upward trend, with solar, reflecting a major increase in the production In 2010, non-renewable energy accounted for nearly 74% of the total energy capacity. However, by 2050, its proportion is predicted to drop by almost half to approximately 35%. In contrast, solar energy, which contributed less than 5% in 2010, is projected to rise to over 37%, making it a major energy source. Biomass and biofuel, as well as water and geothermal, each represented just under 11% of energy capacity in 2010. By 2050, both are expected to increase slightly, reaching around 13% for biomass and biofuel and roughly the same figure for water and geothermal. In summary, while non-renewable energy will lose its dominance by 2050, renewable energy sources, particularly solar, will gain prominence, reflecting a shift towards more sustainable energy solutions.

The given graph predicts the utilisation of different sources of energy like biomass, biofuel, non renewable sources, water and geothermal and solar energy in the year 2050 compared to the year 2010. Overall, the maximum and minimum usage of energy in 2010 has been 75% and 5 % for non renewable energy and biomass and biofuel respectively. In 2050, we aim to increase the consumption of solar energy to almost 40% as compared to 8% in year 2010. Power produced by water and geothermal energy was used upto 11% in 2010 and we donot assume a signiciant change in its consumption in year 2050. However, we would see a major decline in the use of the energy fabricated by non renewable sources from 75% to 35% in year 2050 to 2010. Energy produced from biomass and biofuel was as low as to 5% in year 2010 but we have a dream to push it to atleast to 12% in the year 2050.

THE BAR CHART COMPARSE THE PROPORTION OF ENERGY CAPACITY DERIVED FROM DIFFERENT SOURCES IN 2010 WITH PROJECTIONS FOR 2050. THE SOURCES INCLUDE NON-RENEWABLE ENERGY, BIOMASS AND BIOFUEL, WATER AND GEOTHERMAL, AND SOLAR ENERGY. OVERALL, THERE IS A NOTICEABLE SHIFT FROM RELIANCE ON NON-RENEWABLE ENERGY IN 2010 TO A SIGNIFICANT INCREASE IN THE SHARE OF RENEWABLE SOURCE BY 2050, PARTICULARLY SOLAR ENERGY. IN THE YEAR 2010 NON-RENEWABLE ENERGY DOMINATED THE ENERGY CAPACITY, ACCOUNTING FOR NEARLY 70%, WHILE RENEWABLE SOURCES CONTRIBUTED IN LESS PROPORTIONS. BIOMASS AND BIOFUEL AS WELL AS WATER GEOTHERMAL EACH MADE UPTO 10% OF THE TOTAL. MOREOVER SOLAR ENERGY WAS UTILISED AROUND 5%. BY 2050, NON-RENEWABLE ENERGY IS ESSTIMATED TO DECLINE DRAMATICALLY, ALMOST BY 30%. IN CONTRAST, SOLAR ENERGY IS EXPECTED TO EXPERIENCE THE MOST SUBSTANTIAL GROWTH, RISING FROM 5% IN 2010 TO NEARLY 40% IN 2050 SUPRASSING ALL OTHER RENEWABLE SOURCES. SIMILARLY, THE SHARE OF BIOMASS AND BIOFUEL, AS WELL AS WATER GEOTHERMAL ENERGY ARE PREDICTED TO INCREASE MODERATELY, EACH REACHING ROUGHLY 15% BY 2050. IN SUMMARY, THE DATA SUGGESTS A SIGNIFICANT TRANSITION FROM NON-RENEWABLE TO RENEWABLE ENERGY SOURCES BY 2050, WITH SOLAR ENERGY BY 2050, WITH SOLAR ENERGY EMERGING AS THE PRIMARY CONTRIBUTOR TO THE ENERGY CAPACITY.

The histogram here compares the propotion of energy capacity in 2010 with future analysis of 2050. This is given for the year of 2010 and 2050. Unit used is percentage. Overall, we can see from the graph, that Non-renewable sources of energy will be almost replaced by solar energy.It should be taken into consideration,that water and geothermal energy sources have to bee, more vastly studied upon,as their contribuition to energy resources,almost remains the same. Firstly, to talk about the energy resources in 2010, we can see, around 75% roughly, we were dependent on non-renewable sources of energy. Next major souce comes from the water and geothermal. In a bigger picture, we can note, even in 2010,the biomass and biofuel were not fully researched and practically applied to, for deriving energy from the same. Lastly, in 2050 we can see how much drastically, it has been shifted to solar energy consumption of around 39% and non-renewable energy sources of 33%.The drastic dicline is becauses,non-rewable sources of energy is not replinishable.
